Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Summary:
This version of the css-layout project includes support for .NET projects. Up in the air is how many configurations of .NET projects we allow for, such as Portable Class Libraries, Universal Windows Platform, .NET Core, etc. Still needs integration with Buck.

Summary: Introduce `overflow:scroll` so that scrolling can be implemented without the current overflow:visible hackiness. Currently we use AT_MOST to measure in the cross axis but not in the main axis. This was done to enable scrolling containers where children are not constraint in the main axis by their parent. This caused problems for non-scrolling containers though as it meant that their children cannot be measured correctly in the main axis. Introducing `overflow:scroll` fixes this.

Summary:
Consistently namespace all of css-layout's public C API with "CSS". The only function that needed to be renamed was isUndefined, which I renamed to CSSValueIsUndefined.
Fixes#210.

Summary:
The current CSSLayout can't support RTL because wrong calculation for absolute position.
This change is mainly to fix the issue: https://github.com/facebook/css-layout/issues/197
Three main problems I fixed:
1. Calculate the position in the same way as margin, boarder, and padding. So that to fix the absolute problem.
2. Fix one wrong calculation for leading value when we only know the trailing value. It was hard code for the LTR situation. Now I changed it to depends on the main Axis.
3. Expose getter and setter function for RN to read layout direction and start/end position value.
