   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

   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

       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,

 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

   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.

 # babyjubjub-wasm-example
 - To run it locally needs https://rustwasm.github.io/wasm-pack/installer/ and https://rustwasm.github.io/docs/book/game-of-life/setup.html
 - Rust code lives in `./src/` directory
 - Then, each time that the rust code is modified, just run `./re-build.sh`, which will call wasm-pack build and will serve the html files
 - You can now go to http://127.0.0.1:8080 and the wasm will be running there

 ## About
 [**📚 Read this template tutorial! 📚**][template-docs]
 This template is designed for compiling Rust libraries into WebAssembly and
 publishing the resulting package to NPM.
 Be sure to check out [other `wasm-pack` tutorials online][tutorials] for other
 templates and usages of `wasm-pack`.
 [tutorials]: https://rustwasm.github.io/docs/wasm-pack/tutorials/index.html
 [template-docs]: https://rustwasm.github.io/docs/wasm-pack/tutorials/npm-browser-packages/index.html
 ## 🚴 Usage
 ### 🐑 Use `cargo generate` to Clone this Template
 [Learn more about `cargo generate` here.](https://github.com/ashleygwilliams/cargo-generate)
 ```
 cargo generate --git https://github.com/rustwasm/wasm-pack-template.git --name my-project
 cd my-project
 ```
 ### 🛠️ Build with `wasm-pack build`
 ```
 wasm-pack build
 ```
 ### 🔬 Test in Headless Browsers with `wasm-pack test`
 ```
 wasm-pack test --headless --firefox
 ```
 ### 🎁 Publish to NPM with `wasm-pack publish`
 ```

 ## 🔋 Batteries Included
 * [`wasm-bindgen`](https://github.com/rustwasm/wasm-bindgen) for communicating
  between WebAssembly and JavaScript.
 * [`console_error_panic_hook`](https://github.com/rustwasm/console_error_panic_hook)
  for logging panic messages to the developer console.
 * [`wee_alloc`](https://github.com/rustwasm/wee_alloc), an allocator optimized
  for small code size.
 * `LICENSE-APACHE` and `LICENSE-MIT`: most Rust projects are licensed this way, so these are included for you
 ## License
