+ ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+ INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+ REGARDING THE INFORMATION PROVIDED, AND DISCLAIMS LIABILITY FOR
+ DAMAGES RESULTING FROM ITS USE.
+
+License
+
+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
+TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
+BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
+CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
+CONDITIONS.
+
+1. Definitions
+
+ a. "Adaptation" means a work based upon the Work, or upon the Work and
+ other pre-existing works, such as a translation, adaptation,
+ derivative work, arrangement of music or other alterations of a
+ literary or artistic work, or phonogram or performance and includes
+ cinematographic adaptations or any other form in which the Work may be
+ recast, transformed, or adapted including in any form recognizably
+ derived from the original, except that a work that constitutes a
+ Collection will not be considered an Adaptation for the purpose of
+ this License. For the avoidance of doubt, where the Work is a musical
+ work, performance or phonogram, the synchronization of the Work in
+ timed-relation with a moving image ("synching") will be considered an
+ Adaptation for the purpose of this License.
+ b. "Collection" means a collection of literary or artistic works, such as
+ encyclopedias and anthologies, or performances, phonograms or
+ broadcasts, or other works or subject matter other than works listed
+ in Section 1(f) below, which, by reason of the selection and
+ arrangement of their contents, constitute intellectual creations, in
+ which the Work is included in its entirety in unmodified form along
+ with one or more other contributions, each constituting separate and
+ independent works in themselves, which together are assembled into a
+ collective whole. A work that constitutes a Collection will not be
+ considered an Adaptation (as defined above) for the purposes of this
+ License.
+ c. "Distribute" means to make available to the public the original and
+ copies of the Work or Adaptation, as appropriate, through sale or
+ other transfer of ownership.
+ d. "Licensor" means the individual, individuals, entity or entities that
+ offer(s) the Work under the terms of this License.
+ e. "Original Author" means, in the case of a literary or artistic work,
+ the individual, individuals, entity or entities who created the Work
+ or if no individual or entity can be identified, the publisher; and in
+ addition (i) in the case of a performance the actors, singers,
+ musicians, dancers, and other persons who act, sing, deliver, declaim,
+ play in, interpret or otherwise perform literary or artistic works or
+ expressions of folklore; (ii) in the case of a phonogram the producer
+ being the person or legal entity who first fixes the sounds of a
+ performance or other sounds; and, (iii) in the case of broadcasts, the
+ organization that transmits the broadcast.
+ f. "Work" means the literary and/or artistic work offered under the terms
+ of this License including without limitation any production in the
+ literary, scientific and artistic domain, whatever may be the mode or
+ form of its expression including digital form, such as a book,
+ pamphlet and other writing; a lecture, address, sermon or other work
+ of the same nature; a dramatic or dramatico-musical work; a
+ choreographic work or entertainment in dumb show; a musical
+ composition with or without words; a cinematographic work to which are
+ assimilated works expressed by a process analogous to cinematography;
+ a work of drawing, painting, architecture, sculpture, engraving or
+ lithography; a photographic work to which are assimilated works
+ expressed by a process analogous to photography; a work of applied
+ art; an illustration, map, plan, sketch or three-dimensional work
+ relative to geography, topography, architecture or science; a
+ performance; a broadcast; a phonogram; a compilation of data to the
+ extent it is protected as a copyrightable work; or a work performed by
+ a variety or circus performer to the extent it is not otherwise
+ considered a literary or artistic work.
+ g. "You" means an individual or entity exercising rights under this
+ License who has not previously violated the terms of this License with
+ respect to the Work, or who has received express permission from the
+ Licensor to exercise rights under this License despite a previous
+ violation.
+ h. "Publicly Perform" means to perform public recitations of the Work and
+ to communicate to the public those public recitations, by any means or
+ process, including by wire or wireless means or public digital
+ performances; to make available to the public Works in such a way that
+ members of the public may access these Works from a place and at a
+ place individually chosen by them; to perform the Work to the public
+ by any means or process and the communication to the public of the
+ performances of the Work, including by public digital performance; to
+ broadcast and rebroadcast the Work by any means including signs,
+ sounds or images.
+ i. "Reproduce" means to make copies of the Work by any means including
+ without limitation by sound or visual recordings and the right of
+ fixation and reproducing fixations of the Work, including storage of a
+ protected performance or phonogram in digital form or other electronic
+ medium.
+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce,
+limit, or restrict any uses free from copyright or rights arising from
+limitations or exceptions that are provided for in connection with the
+copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+ a. to Reproduce the Work, to incorporate the Work into one or more
+ Collections, and to Reproduce the Work as incorporated in the
+ Collections;
+ b. to create and Reproduce Adaptations provided that any such Adaptation,
+ including any translation in any medium, takes reasonable steps to
+ clearly label, demarcate or otherwise identify that changes were made
+ to the original Work. For example, a translation could be marked "The
+ original work was translated from English to Spanish," or a
+ modification could indicate "The original work has been modified.";
+ c. to Distribute and Publicly Perform the Work including as incorporated
+ in Collections; and,
+ d. to Distribute and Publicly Perform Adaptations.
+ e. For the avoidance of doubt:
+
+ i. Non-waivable Compulsory License Schemes. In those jurisdictions in
+ which the right to collect royalties through any statutory or
+ compulsory licensing scheme cannot be waived, the Licensor
+ reserves the exclusive right to collect such royalties for any
+ exercise by You of the rights granted under this License;
+ ii. Waivable Compulsory License Schemes. In those jurisdictions in
+ which the right to collect royalties through any statutory or
+ compulsory licensing scheme can be waived, the Licensor waives the
+ exclusive right to collect such royalties for any exercise by You
+ of the rights granted under this License; and,
+ iii. Voluntary License Schemes. The Licensor waives the right to
+ collect royalties, whether individually or, in the event that the
+ Licensor is a member of a collecting society that administers
+ voluntary licensing schemes, via that society, from any exercise
+ by You of the rights granted under this License.
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights in
+other media and formats. Subject to Section 8(f), all rights not expressly
+granted by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made
+subject to and limited by the following restrictions:
+
+ a. You may Distribute or Publicly Perform the Work only under the terms
+ of this License. You must include a copy of, or the Uniform Resource
+ Identifier (URI) for, this License with every copy of the Work You
+ Distribute or Publicly Perform. You may not offer or impose any terms
+ on the Work that restrict the terms of this License or the ability of
+ the recipient of the Work to exercise the rights granted to that
+ recipient under the terms of the License. You may not sublicense the
+ Work. You must keep intact all notices that refer to this License and
+ to the disclaimer of warranties with every copy of the Work You
+ Distribute or Publicly Perform. When You Distribute or Publicly
+ Perform the Work, You may not impose any effective technological
+ measures on the Work that restrict the ability of a recipient of the
+ Work from You to exercise the rights granted to that recipient under
+ the terms of the License. This Section 4(a) applies to the Work as
+ incorporated in a Collection, but this does not require the Collection
+ apart from the Work itself to be made subject to the terms of this
+ License. If You create a Collection, upon notice from any Licensor You
+ must, to the extent practicable, remove from the Collection any credit
+ as required by Section 4(b), as requested. If You create an
+ Adaptation, upon notice from any Licensor You must, to the extent
+ practicable, remove from the Adaptation any credit as required by
+ Section 4(b), as requested.
+ b. If You Distribute, or Publicly Perform the Work or any Adaptations or
+ Collections, You must, unless a request has been made pursuant to
+ Section 4(a), keep intact all copyright notices for the Work and
+ provide, reasonable to the medium or means You are utilizing: (i) the
+ name of the Original Author (or pseudonym, if applicable) if supplied,
+ and/or if the Original Author and/or Licensor designate another party
+ or parties (e.g., a sponsor institute, publishing entity, journal) for
+ attribution ("Attribution Parties") in Licensor's copyright notice,
+ terms of service or by other reasonable means, the name of such party
+ or parties; (ii) the title of the Work if supplied; (iii) to the
+ extent reasonably practicable, the URI, if any, that Licensor
+ specifies to be associated with the Work, unless such URI does not
+ refer to the copyright notice or licensing information for the Work;
+ and (iv) , consistent with Section 3(b), in the case of an Adaptation,
+ a credit identifying the use of the Work in the Adaptation (e.g.,
+ "French translation of the Work by Original Author," or "Screenplay
+ based on original Work by Original Author"). The credit required by
+ this Section 4 (b) may be implemented in any reasonable manner;
+ provided, however, that in the case of a Adaptation or Collection, at
+ a minimum such credit will appear, if a credit for all contributing
+ authors of the Adaptation or Collection appears, then as part of these
+ credits and in a manner at least as prominent as the credits for the
+ other contributing authors. For the avoidance of doubt, You may only
+ use the credit required by this Section for the purpose of attribution
+ in the manner set out above and, by exercising Your rights under this
+ License, You may not implicitly or explicitly assert or imply any
+ connection with, sponsorship or endorsement by the Original Author,
+ Licensor and/or Attribution Parties, as appropriate, of You or Your
+ use of the Work, without the separate, express prior written
+ permission of the Original Author, Licensor and/or Attribution
+ Parties.
+ c. Except as otherwise agreed in writing by the Licensor or as may be
+ otherwise permitted by applicable law, if You Reproduce, Distribute or
+ Publicly Perform the Work either by itself or as part of any
+ Adaptations or Collections, You must not distort, mutilate, modify or
+ take other derogatory action in relation to the Work which would be
+ prejudicial to the Original Author's honor or reputation. Licensor
+ agrees that in those jurisdictions (e.g. Japan), in which any exercise
+ of the right granted in Section 3(b) of this License (the right to
+ make Adaptations) would be deemed to be a distortion, mutilation,
+ modification or other derogatory action prejudicial to the Original
+ Author's honor and reputation, the Licensor will waive or not assert,
+ as appropriate, this Section, to the fullest extent permitted by the
+ applicable national law, to enable You to reasonably exercise Your
+ right under Section 3(b) of this License (right to make Adaptations)
+ but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
+OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
+LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
+ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
+ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+ a. This License and the rights granted hereunder will terminate
+ automatically upon any breach by You of the terms of this License.
+ Individuals or entities who have received Adaptations or Collections
+ from You under this License, however, will not have their licenses
+ terminated provided such individuals or entities remain in full
+ compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
+ survive any termination of this License.
+ b. Subject to the above terms and conditions, the license granted here is
+ perpetual (for the duration of the applicable copyright in the Work).
+ Notwithstanding the above, Licensor reserves the right to release the
+ Work under different license terms or to stop distributing the Work at
+ any time; provided, however that any such election will not serve to
+ withdraw this License (or any other license that has been, or is
+ required to be, granted under the terms of this License), and this
+ License will continue in full force and effect unless terminated as
+ stated above.
+
+8. Miscellaneous
+
+ a. Each time You Distribute or Publicly Perform the Work or a Collection,
+ the Licensor offers to the recipient a license to the Work on the same
+ terms and conditions as the license granted to You under this License.
+ b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
+ offers to the recipient a license to the original Work on the same
+ terms and conditions as the license granted to You under this License.
+ c. If any provision of this License is invalid or unenforceable under
+ applicable law, it shall not affect the validity or enforceability of
+ the remainder of the terms of this License, and without further action
+ by the parties to this agreement, such provision shall be reformed to
+ the minimum extent necessary to make such provision valid and
+ enforceable.
+ d. No term or provision of this License shall be deemed waived and no
+ breach consented to unless such waiver or consent shall be in writing
+ and signed by the party to be charged with such waiver or consent.
+ e. This License constitutes the entire agreement between the parties with
+ respect to the Work licensed here. There are no understandings,
+ agreements or representations with respect to the Work not specified
+ here. Licensor shall not be bound by any additional provisions that
+ may appear in any communication from You. This License may not be
+ modified without the mutual written agreement of the Licensor and You.
+ f. The rights granted under, and the subject matter referenced, in this
+ License were drafted utilizing the terminology of the Berne Convention
+ for the Protection of Literary and Artistic Works (as amended on
+ September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
+ Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+- Demonstrating empathy and kindness toward other people
+- Being respectful of differing opinions, viewpoints, and experiences
+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our mistakes,
+ and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the overall
+ community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or advances of
+ any kind
+- Trolling, insulting or derogatory comments, and personal or political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email address,
+ without their explicit permission
+- Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the ombudspersons
+markus.quante@hereon.de or sabine.mendach@hereon.de.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage],
+version 2.1, available at
+[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html][v2.1].
+
+Community Impact Guidelines were inspired by
+[Mozilla's code of conduct enforcement ladder][Mozilla CoC].

+# Coding standard
+
+We hope you find it easy to read our code and understand its structure. When you contribute code to our project, we ask you to adhere to coding standards, the most important one is consistency with the current code.
+
+## Coding rules
+
+1. Consistency
+ : Whatever you do, be consistent in what you do. This is the guiding principle all other rules are subjected to
+
+2. Line break
+ : Please break at 132 columns at the latest
+
+3. Empty lines.
+ : Do not overuse empty lines, but reserve them for separating logical units or blocks of statements, just like
+ you would use paragraphs in a text. Separate procedures with one empty line.
+
+4. Indentation
+ Use consistent and logical indentation to make the code more readable. Each level of indentation should consist of three spaces.
+
+5. Naming conventions
+ : Use meaningful english names for variables, procedures, and functions. Names should be descriptive and use lowercase letters.
+
+6. Comments:
+ : Use comments to explain complex sections of code, as well as to provide an overview of what the code does.
+
+7. Error handling:
+ Always include error handling code to catch and handle unexpected exceptions. Preferably either halt the simulation with `stop`. Use appropriate error messages to help users diagnose and fix problems.
+
+8. Documentation:
+ Provide documentation for the code, including a description of its purpose, its input and output parameters, and examples of its usage.

+
+(b) To the maximum extent permitted by the relevant law, You grant to Us a perpetual, worldwide, non-exclusive, transferable, royalty-free, irrevocable license under the Copy<!-- /-->right covering the Contribution, with the right to sublicense such rights through multiple tiers of sublicensees, to reproduce, modify, display, perform and distribute the Contribution as part of the Material; provided that this license is conditioned upon compliance with Section 2.3.
+

+
+# Disclaimer
+
+EXCEPT FOR THE EXPRESS WARRANTIES IN SECTION 3, THE CONTRIBUTION IS PROVIDED "AS IS". MORE PARTICULARLY, ALL EXPRESS OR IMPLIED WARRANTIES INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT ARE EXPRESSLY DISCLAIMED BY YOU TO US [AND BY US TO YOU]. TO THE EXTENT THAT ANY SUCH WARRANTIES CANNOT BE DISCLAIMED, SUCH WARRANTY IS LIMITED IN DURATION TO THE MINIMUM PERIOD PERMITTED BY LAW.
+
+# Consequential Damage Waiver

+TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL YOU [OR US] BE LIABLE FOR ANY LOSS OF PROFITS, LOSS OF ANTICIPATED SAVINGS, LOSS OF DATA, INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL AND EXEMPLARY DAMAGES ARISING OUT OF THIS AGREEMENT REGARDLESS OF THE LEGAL OR EQUITABLE THEORY (CONTRACT, TORT OR OTHERWISE) UPON WHICH THE CLAIM IS BASED.
+
+# Miscellaneous
+
+This Agreement will be governed by and construed in accordance with the laws of Germany excluding its conflicts of law provisions. Under certain circumstances, the governing law in this section might be superseded by the United Nations Convention on Contracts for the International Sale of Goods ("UN Convention") and the parties intend to avoid the application of the UN Convention to this Agreement and, thus, exclude the application of the UN Convention in its entirety to this Agreement.
+
+This Agreement sets out the entire agreement between You and Us for Your Contributions to Us and overrides all other agreements or understandings.
+
+If You or We assign the rights or obligations received through this Agreement to a third party, as a condition of the assignment, that third party must agree in writing to abide by all the rights and obligations in the Agreement.
+
+The failure of either party to require performance by the other party of any provision of this Agreement in one situation shall not affect the right of a party to require such performance at any time in the future. A waiver of performance under a provision in one situation shall not be considered a waiver of the performance of the provision in the future or a waiver of the provision in its entirety.
+
+If any provision of this Agreement is found void and unenforceable, such provision will be replaced to the extent possible with a provision that comes closest to the meaning of the original provision and which is enforceable. The terms and conditions set forth in this Agreement shall apply notwithstanding any failure of essential purpose of this Agreement or any limited remedy to the maximum extent possible under law.
