 Creative Commons Corporation (“Creative Commons”) is not a law firm and does
 not provide legal services or legal advice. Distribution of Creative Commons
 public licenses does not create a lawyer-client or other relationship.
 Creative Commons makes its licenses and related information available on an
 “as-is” basis. Creative Commons gives no warranties regarding its licenses,
 any material licensed under their terms and conditions, or any related
 information. Creative Commons disclaims all liability for damages resulting
 from their use to the fullest extent possible. Using Creative Commons Public
 Licenses Creative Commons public licenses provide a standard set of terms and
 conditions that creators and other rights holders may use to share original
 works of authorship and other material subject to copyright and certain other
 rights specified in the public license below. The following considerations
 are for informational purposes only, are not exhaustive, and do not form part
 of our licenses. Considerations for licensors: Our public licenses are
 intended for use by those authorized to give the public permission to use
 material in ways otherwise restricted by copyright and certain other rights.
 Our licenses are irrevocable. Licensors should read and understand the terms
 and conditions of the license they choose before applying it. Licensors
 should also secure all rights necessary before applying our licenses so that
 the public can reuse the material as expected. Licensors should clearly mark
 any material not subject to the license. This includes other CC-licensed
 material, or material used under an exception or limitation to copyright.
 More considerations for licensors. Considerations for the public: By using
 one of our public licenses, a licensor grants the public permission to use
 the licensed material under specified terms and conditions. If the licensor’s
 permission is not necessary for any reason–for example, because of any
 applicable exception or limitation to copyright–then that use is not
 regulated by the license. Our licenses grant only permissions under copyright
 and certain other rights that a licensor has authority to grant. Use of
 the licensed material may still be restricted for other reasons, including
 because others have copyright or other rights in the material. A licensor
 may make special requests, such as asking that all changes be marked or
 described. Although not required by our licenses, you are encouraged to
 respect those requests where reasonable. More considerations for the public.

 Creative Commons Attribution-ShareAlike 4.0 International Public License
 .
 By exercising the Licensed Rights (defined below), You accept and agree
 to be bound by the terms and conditions of this Creative Commons
 Attribution-ShareAlike 4.0 International Public License ("Public License").
 To the extent this Public License may be interpreted as a contract, You are
 granted the Licensed Rights in consideration of Your acceptance of these
 terms and conditions, and the Licensor grants You such rights in consideration
 of benefits the Licensor receives from making the Licensed Material available
 under these terms and conditions.
 .
 Section 1 – Definitions.
 .
  a. Adapted Material means material subject to Copyright and Similar Rights
  that is derived from or based upon the Licensed Material and in which the
  Licensed Material is translated, altered, arranged, transformed, or
  otherwise modified in a manner requiring permission under the Copyright
  and Similar Rights held by the Licensor. For purposes of this Public
  License, where the Licensed Material is a musical work, performance, or
  sound recording, Adapted Material is always produced where the Licensed
  Material is synched in timed relation with a moving image.

  Similar Rights in Your contributions to Adapted Material in accordance
  with the terms and conditions of this Public License.
 .

  as essentially the equivalent of this Public License.
 .
  d. Copyright and Similar Rights means copyright and/or similar rights closely
  related to copyright including, without limitation, performance,
  broadcast, sound recording, and Sui Generis Database Rights, without
  regard to how the rights are labeled or categorized. For purposes of this
  Public License, the rights specified in Section 2(b)(1)-(2) are not
  Copyright and Similar Rights.
 .
  e. Effective Technological Measures means those measures that, in the absence
  of proper authority, may not be circumvented under laws fulfilling
  obligations under Article 11 of the WIPO Copyright Treaty adopted on
  December 20, 1996, and/or similar international agreements.
 .
  f. Exceptions and Limitations means fair use, fair dealing, and/or any other
  exception or limitation to Copyright and Similar Rights that applies to
  Your use of the Licensed Material.
 .
  g. License Elements means the license attributes listed in the name of a
  Creative Commons Public License. The License Elements of this Public
  License are Attribution and ShareAlike.
 .
  h. Licensed Material means the artistic or literary work, database, or other
  material to which the Licensor applied this Public License.
 .
  i. Licensed Rights means the rights granted to You subject to the terms and
  conditions of this Public License, which are limited to all Copyright and
  Similar Rights that apply to Your use of the Licensed Material and that
  the Licensor has authority to license.
 .
  j. Licensor means the individual(s) or entity(ies) granting rights under this
  Public License.
 .
  k. Share means to provide material to the public by any means or process that
  requires permission under the Licensed Rights, such as reproduction,
  public display, public performance, distribution, dissemination,
  communication, or importation, and to make material available to the
  public including in ways that members of the public may access the
  material from a place and at a time individually chosen by them.
 .
  l. Sui Generis Database Rights means rights other than copyright resulting
  from Directive 96/9/EC of the European Parliament and of the Council of
  11 March 1996 on the legal protection of databases, as amended and/or
  succeeded, as well as other essentially equivalent rights anywhere in the
  world.
 .
  m. You means the individual or entity exercising the Licensed Rights under
  this Public License. Your has a corresponding meaning.
 .
 Section 2 – Scope.
 .
  a. License grant.
 .
      1. Subject to the terms and conditions of this Public License, the
      Licensor hereby grants You a worldwide, royalty-free,
      non-sublicensable, non-exclusive, irrevocable license to exercise
      the Licensed Rights in the Licensed Material to:
 .
         A. reproduce and Share the Licensed Material, in whole or in part; and
         B. produce, reproduce, and Share Adapted Material.
 .
      2. Exceptions and Limitations. For the avoidance of doubt, where
      Exceptions and Limitations apply to Your use, this Public License
      does not apply, and You do not need to comply with its terms and
      conditions.
 .
      3. Term. The term of this Public License is specified in Section 6(a).
 .
      4. Media and formats; technical modifications allowed. The Licensor
      authorizes You to exercise the Licensed Rights in all media and
      formats whether now known or hereafter created, and to make
      technical modifications necessary to do so. The Licensor waives
      and/or agrees not to assert any right or authority to forbid You
      from making technical modifications necessary to exercise the
      Licensed Rights, including technical modifications necessary to
      circumvent Effective Technological Measures. For purposes of this
      Public License, simply making modifications authorized by this
      Section 2(a)(4) never produces Adapted Material.
 .
      5. Downstream recipients.
 .
         A. Offer from the Licensor – Licensed Material. Every recipient of
         the Licensed Material automatically receives an offer from the
         Licensor to exercise the Licensed Rights under the terms and
         conditions of this Public License.
 .
         B. Additional offer from the Licensor – Adapted Material. Every
         recipient of Adapted Material from You automatically receives an
         offer from the Licensor to exercise the Licensed Rights in the
         Adapted Material under the conditions of the Adapter’s License
         You apply.
 .
         C. No downstream restrictions. You may not offer or impose any
         additional or different terms or conditions on, or apply any
         Effective Technological Measures to, the Licensed Material if
         doing so restricts exercise of the Licensed Rights by any
         recipient of the Licensed Material.
 .
      6. No endorsement. Nothing in this Public License constitutes or may be
      construed as permission to assert or imply that You are, or that Your
      use of the Licensed Material is, connected with, or sponsored,
      endorsed, or granted official status by, the Licensor or others
      designated to receive attribution as provided in Section 3(a)(1)(A)(i).
 .
  b. Other rights.
 .
      1. Moral rights, such as the right of integrity, are not licensed under
      this Public License, nor are publicity, privacy, and/or other similar
      personality rights; however, to the extent possible, the Licensor
      waives and/or agrees not to assert any such rights held by the
      Licensor to the limited extent necessary to allow You to exercise the
      Licensed Rights, but not otherwise.
 .
      2. Patent and trademark rights are not licensed under this Public License.
 .
      3. To the extent possible, the Licensor waives any right to collect
      royalties from You for the exercise of the Licensed Rights, whether
      directly or through a collecting society under any voluntary or
      waivable statutory or compulsory licensing scheme. In all other
      cases the Licensor expressly reserves any right to collect such
      royalties.
 .
 Section 3 – License Conditions.
 .
 Your exercise of the Licensed Rights is expressly made subject to the
 following conditions.
 .
  a. Attribution.
 .
      1. If You Share the Licensed Material (including in modified form),
      You must:
 .
         A. retain the following if it is supplied by the Licensor with
         the Licensed Material:
 .
            i. identification of the creator(s) of the Licensed Material
            and any others designated to receive attribution, in any
            reasonable manner requested by the Licensor (including by
            pseudonym if designated);
 .
            ii. a copyright notice;
 .
            iii. a notice that refers to this Public License;

         B. indicate if You modified the Licensed Material and retain an
         indication of any previous modifications; and

         C. indicate the Licensed Material is licensed under this Public
         License, and include the text of, or the URI or hyperlink to,
         this Public License.
 .
      2. You may satisfy the conditions in Section 3(a)(1) in any reasonable
      manner based on the medium, means, and context in which You Share
      the Licensed Material. For example, it may be reasonable to satisfy
      the conditions by providing a URI or hyperlink to a resource that
      includes the required information.
 .
      3. If requested by the Licensor, You must remove any of the information
      required by Section 3(a)(1)(A) to the extent reasonably practicable.

     Adapted Material You produce, the following conditions also apply.

      with the same License Elements, this version or later, or a BY-SA
      Compatible License.
 .
      2. You must include the text of, or the URI or hyperlink to, the
      Adapter's License You apply. You may satisfy this condition in
      any reasonable manner based on the medium, means, and context in
      which You Share Adapted Material.
 .
      3. You may not offer or impose any additional or different terms or
      conditions on, or apply any Effective Technological Measures to,
      Adapted Material that restrict exercise of the rights granted under
      the Adapter's License You apply.
 .
 Section 4 – Sui Generis Database Rights.
 .
 Where the Licensed Rights include Sui Generis Database Rights that apply to
 Your use of the Licensed Material:
 .
  a. for the avoidance of doubt, Section 2(a)(1) grants You the right to
  extract, reuse, reproduce, and Share all or a substantial portion of
  the contents of the database;
 .
  b. if You include all or a substantial portion of the database contents
  in a database in which You have Sui Generis Database Rights, then the
  database in which You have Sui Generis Database Rights (but not its
  individual contents) is Adapted Material, including for purposes of
  Section 3(b); and
 .
  c. You must comply with the conditions in Section 3(a) if You Share all
  or a substantial portion of the contents of the database.
  For the avoidance of doubt, this Section 4 supplements and does not
  replace Your obligations under this Public License where the Licensed
  Rights include other Copyright and Similar Rights.
 .
 Section 5 – Disclaimer of Warranties and Limitation of Liability.
 .
  a. Unless otherwise separately undertaken by the Licensor, to the extent
  possible, the Licensor offers the Licensed Material as-is and
  as-available, and makes no representations or warranties of any kind
  concerning the Licensed Material, whether express, implied, statutory,
  or other. This includes, without limitation, warranties of title,
  merchantability, fitness for a particular purpose, non-infringement,
  absence of latent or other defects, accuracy, or the presence or
  absence of errors, whether or not known or discoverable. Where
  disclaimers of warranties are not allowed in full or in part, this
  disclaimer may not apply to You.
 .
  b. To the extent possible, in no event will the Licensor be liable to
  You on any legal theory (including, without limitation, negligence)
  or otherwise for any direct, special, indirect, incidental,
  consequential, punitive, exemplary, or other losses, costs, expenses,
  or damages arising out of this Public License or use of the Licensed
  Material, even if the Licensor has been advised of the possibility of
  such losses, costs, expenses, or damages. Where a limitation of
  liability is not allowed in full or in part, this limitation may not
  apply to You.
 .
  c. The disclaimer of warranties and limitation of liability provided above
  shall be interpreted in a manner that, to the extent possible, most
  closely approximates an absolute disclaimer and waiver of all liability.
 .

  Rights licensed here. However, if You fail to comply with this Public
  License, then Your rights under this Public License terminate

  Section 6(a), it reinstates:

      1. automatically as of the date the violation is cured, provided it
      is cured within 30 days of Your discovery of the violation; or
 .
      2. upon express reinstatement by the Licensor.
 .
  c. For the avoidance of doubt, this Section 6(b) does not affect any right
  the Licensor may have to seek remedies for Your violations of this Public
  License.
 .
  d. For the avoidance of doubt, the Licensor may also offer the Licensed
  Material under separate terms or conditions or stop distributing the
  Licensed Material at any time; however, doing so will not terminate

 .
 Section 7 – Other Terms and Conditions.
 .
  a. The Licensor shall not be bound by any additional or different terms

  not be interpreted to, reduce, limit, restrict, or impose conditions
  on any use of the Licensed Material that could lawfully be made without
  permission under this Public License.
 .
  b. To the extent possible, if any provision of this Public License is
  deemed unenforceable, it shall be automatically reformed to the minimum
  extent necessary to make it enforceable. If the provision cannot be
  reformed, it shall be severed from this Public License without affecting
  the enforceability of the remaining terms and conditions.
 .
  c. No term or condition of this Public License will be waived and no
  failure to comply consented to unless expressly agreed to by the
  Licensor.
 .

  limitation upon, or waiver of, any privileges and immunities that apply
  to the Licensor or You, including from the legal processes of any
  jurisdiction or authority.
