        purposes of this definition, "control" means (i) the power, direct or indirect, to 
        cause the direction or management of such entity, whether by contract or otherwise, 
        or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii)

        "You" (or "Your") shall mean an individual or Legal Entity exercising permissions 
        granted by this License.

        "Source" form shall mean the preferred form for making modifications, including but 
        not limited to software source code, documentation source, and configuration files.

        "Object" form shall mean any form resulting from mechanical transformation or translation 
        of a Source form, including but not limited to compiled object code, generated documentation, 
        and conversions to other media types.

        "Work" shall mean the work of authorship, whether in Source or Object form, made 
        available under the License, as indicated by a copyright notice that is included in 
        or attached to the work (an example is provided in the Appendix below).

        "Derivative Works" shall mean any work, whether in Source or Object form, that is 
        based on (or derived from) the Work and for which the editorial revisions, annotations, 
        elaborations, or other modifications represent, as a whole, an original work of 
        authorship. For the purposes of this License, Derivative Works shall not include 
        works that remain separable from, or merely link (or bind by name) to the interfaces 
        of, the Work and Derivative Works thereof.

        "Contribution" shall mean any work of authorship, including the original version of the 
        Work and any modifications or additions to that Work or Derivative Works thereof, that 
        is intentionally submitted to Licensor for inclusion in the Work by the copyright owner 
        or by an individual or Legal Entity authorized to submit on behalf of the copyright owner. 
        For the purposes of this definition, "submitted" means any form of electronic, verbal, 
        or written communication sent to the Licensor or its representatives, including but not 
        limited to communication on electronic mailing lists, source code control systems, and 
        issue tracking systems that are managed by, or on behalf of, the Licensor for the purpose 
        of discussing and improving the Work, but excluding communication that is conspicuously 
        marked or otherwise designated in writing by the copyright owner as "Not a Contribution."

        "Contributor" shall mean Licensor and any individual or Legal Entity on behalf of whom a 
        Contribution has been received by Licensor and subsequently incorporated within the Work.

        2. Grant of Copyright License.

        Subject to the terms and conditions of this License, each Contributor hereby grants to 
        You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright 
        license to reproduce, prepare Derivative Works of, publicly display, publicly perform, 
        sublicense, and distribute the Work and such Derivative Works in Source or Object form.

        3. Grant of Patent License.

        Subject to the terms and conditions of this License, each Contributor hereby grants to 
        You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except 
        as stated in this section) patent license to make, have made, use, offer to sell, sell, 
        import, and otherwise transfer the Work, where such license applies only to those patent 
        claims licensable by such Contributor that are necessarily infringed by their 
        Contribution(s) alone or by combination of their Contribution(s) with the Work to which 
        such Contribution(s) was submitted. If You institute patent litigation against any entity 
        (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a 
        Contribution incorporated within the Work constitutes direct or contributory patent 
        infringement, then any patent licenses granted to You under this License for that Work 
        shall terminate as of the date such litigation is filed. Any patent license granted hereby 
        with respect to contributions by an individual employed by an institution or organization 
        is limited to patent claims where the individual that is the author of the Work is also 
        the inventor of the patent claims licensed, and where the organization or institution 
        has the right to grant such license under applicable grant and research funding 
        agreements. No other express or implied licenses are granted.

        4. Redistribution.

        You may reproduce and distribute copies of the Work or Derivative Works thereof in any 
        medium, with or without modifications, and in Source or Object form, provided that You 
        meet the following conditions:

        You must give any other recipients of the Work or Derivative Works a copy of this License; and
        You must cause any modified files to carry prominent notices stating that You changed the files; and
        You must retain, in the Source form of any Derivative Works that You distribute, all copyright, 
        patent, trademark, and attribution notices from the Source form of the Work, excluding those 
        notices that do not pertain to any part of the Derivative Works; and
        If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative 
        Works that You distribute must include a readable copy of the attribution notices contained 
        within such NOTICE file, excluding those notices that do not pertain to any part of the 
        Derivative Works, in at least one of the following places: within a NOTICE text file 
        distributed as part of the Derivative Works; within the Source form or documentation, if 
        provided along with the Derivative Works; or, within a display generated by the Derivative 
        Works, if and wherever such third-party notices normally appear. The contents of the NOTICE 
        file are for informational purposes only and do not modify the License. You may add Your own 
        attribution notices within Derivative Works that You distribute, alongside or as an addendum 
        to the NOTICE text from the Work, provided that such additional attribution notices cannot be 
        construed as modifying the License.

        You may add Your own copyright statement to Your modifications and may provide additional or 
        different license terms and conditions for use, reproduction, or distribution of Your 
        modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, 
        and distribution of the Work otherwise complies with the conditions stated in this License.

        5. Submission of Contributions.

        Unless You explicitly state otherwise, any Contribution intentionally submitted for inclusion 
        in the Work by You to the Licensor shall be under the terms and conditions of this License, 
        without any additional terms or conditions. Notwithstanding the above, nothing herein shall 
        supersede or modify the terms of any separate license agreement you may have executed with 
        Licensor regarding such Contributions.

        6. Trademarks.

        This License does not grant permission to use the trade names, trademarks, service marks, 
        or product names of the Licensor, except as required for reasonable and customary use in 
        describing the origin of the Work and reproducing the content of the NOTICE file.

        7. Disclaimer of Warranty.

        Unless required by applicable law or agreed to in writing, Licensor provides the Work 
        (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES 
        OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any 
        warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A 
        PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of 
        using or redistributing the Work and assume any risks associated with Your exercise of 
        permissions under this License.

        8. Limitation of Liability.

        In no event and under no legal theory, whether in tort (including negligence), contract, 
        or otherwise, unless required by applicable law (such as deliberate and grossly negligent 
        acts) or agreed to in writing, shall any Contributor be liable to You for damages, including 
        any direct, indirect, special, incidental, or consequential damages of any character arising 
        as a result of this License or out of the use or inability to use the Work (including but 
        not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, 
        or any and all other commercial damages or losses), even if such Contributor has been advised 
        of the possibility of such damages.

        9. Accepting Warranty or Additional Liability.

        While redistributing the Work or Derivative Works thereof, You may choose to offer, and 
        charge a fee for, acceptance of support, warranty, indemnity, or other liability 
        obligations and/or rights consistent with this License. However, in accepting such 
        obligations, You may act only on Your own behalf and on Your sole responsibility, not 
        on behalf of any other Contributor, and only if You agree to indemnify, defend, and 
        hold each Contributor harmless for any liability incurred by, or claims asserted against, 
        such Contributor by reason of your accepting any such warranty or additional liability.
