Summary: - As mentioned in the title, this PR adds Javascript support to Yoga. Two different builds are included in this PR thanks to [nbind](https://github.com/charto/nbind), which conveniently allow to target both Node.js' native addons and browser environments via asmjs with approximately the same codebase. That should solve #215. - All tests successfully pass on both codepaths. You can run `yarn test:all` inside the `javascript` directory to test it. - Because of a bug in nbind, the [following PR](https://github.com/charto/nbind/pull/57) needs to be merged and a new version released before this one can be safely merged as well. - I had to use `double` types instead of `float` in the C++ bindings because of an Emscripten [bug](https://github.com/kripken/emscripten/issues/3592) where symbols aren't correctly exported when using floats. - There's some tweaks to do before this PR is 100% ready to merge, but I wanted to have your opinion first. What do you think of this? --- To do: - [x] Ensure th Closes https://github.com/facebook/yoga/pull/304 Reviewed By: mikearmstrong001 Differential Revision: D4375187 Pulled By: emilsjolander fbshipit-source-id: 47248558a9506b7c512b5ef281cd12fe1a60cab7
