Summary: Using shared code for reuse in other platforms based on iOS native implementation. Adds YogaKit sample. Adds YogaKit tests (same as objc). ``` YogaKitTest : 80 ms Facebook.YogaKit.iOS.Tests.exe : 81 ms Tests run: 11 Passed: 8 Inconclusive: 0 Failed: 3 Ignored: 1 ``` Since we don't have extension properties we need to go with a extension method to get access to the YogaLayout . I m also not sure this is leak free yet, would love some help with testing and feedback about view/node lifecycle Closes https://github.com/facebook/yoga/pull/336 Reviewed By: splhack Differential Revision: D4415027 Pulled By: emilsjolander fbshipit-source-id: c88328212426c3200e6f0c48cda594cd2c432065
