   *        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

   *
   *        "Contributor" shall mean Licensor and any individual or Legal Entity

   *        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

   *        (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.
   *
   *     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:
   *
   *        (a) You must give any other recipients of the Work or
   *            Derivative Works a copy of this License; and
   *
   *        (b) You must cause any modified files to carry prominent notices
   *            stating that You changed the files; and
   *
   *        (c) 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
   *
   *        (d) 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.
   *
   *     END OF TERMS AND CONDITIONS
   *
   *     APPENDIX: How to apply the Apache License to your work.
   *
   *        To apply the Apache License to your work, attach the following
   *        boilerplate notice, with the fields enclosed by brackets "[]"
