Summary: Adds the feature to use percentage as a value unit. You can use the function ```YGPx(float)``` and ```YGPercent(float)``` for convenience. I did some benchmarks: ``` Without Percentage Feature - Release x86: Stack with flex: median: 0.000000 ms, stddev: 0.146683 ms Align stretch in undefined axis: median: 0.000000 ms, stddev: 0.136525 ms Nested flex: median: 0.000000 ms, stddev: 0.490101 ms Huge nested layout: median: 23.000000 ms, stddev: 0.928291 ms Stack with flex: median: 0.000000 ms, stddev: 0.170587 ms Align stretch in undefined axis: median: 0.000000 ms, stddev: 0.143384 ms Nested flex: median: 0.000000 ms, stddev: 0.477791 ms Huge nested layout: median: 22.000000 ms, stddev: 2.129779 ms With Percentage Feature - Release x86: Stack with flex: median: 0.000000 ms, stddev: 0.132951 ms Align stretch in undefined axis: median: 0.000000 ms, stddev: 0.136525 ms Nested flex: median: 0.000000 ms, stddev: 0.489570 ms Huge nested layout: median: 21.000000 ms, stddev: 1.390476 ms Closes https://github.com/facebook/yoga/pull/258 Reviewed By: dshahidehpour Differential Revision: D4361945 Pulled By: emilsjolander fbshipit-source-id: a8f5bc63ad352eb9410d792729e56664468cd76a
