Summary:
Make default init unavailable, as it will not initialise `YGNode` which is required for the setters
and getters of YGLayout's properties to work properly. In setters and getters we call the corresponding `YGNode`'s setters and getters. Thus the following code will crash
```
let layout = YGLayout()
layout.flexDirection = .row
```

Summary:
Changes so we are able to reset properties to their initial value.
This is required to reset these properties.
Add the support of YGUnitUndefined to many properties:
* minWidth
* maxWidth
* minHeight
* maxHeight
Also, these properties must be reset to YGUnitAuto.
* width
* height
* flexBasis
This now matches completely how these properties are initialized in Yoga.cpp

Summary: For our -objc efforts we'll be excluding vendorlibs from these changes for now and then working on getting them to not have to be fully linked as a second effort. The way -objc flag works is its an all or nothing flag for the app and thus for any library we still want to link completely we'll have to add a link_whole = True to the BUCK file. (Otherwise we'll have crashes in these libraries :P).

Summary:
We still need to wait for the `YGUnitPoint` PR to be merged :) But please let me know what you think. One caveat: because of a limitation of Swift, a literal value can be automatically understood as a point-based `YGValue`, but variables have to be explicitly cast. I haven't found a way around it yet:
```
view.yoga.width = 10 // value == 10, unit == YGUnitPixel
let a: CGFloat = 100
view.yoga.height = a // Compiler error
view.yoga.height = YGValue(a) // works, not great

Summary:
The main container that gets called `applyLayoutPreservingOrigin:` is using its size as a fixed bounding box.
In some cases it's preferrable to let it accomodate its contents.
This diffs extends `applyLayoutPreservingOrigin:` by adding an additional parameter which can be used to sepecify whether width and/or height are fixed or flexible.
Feel free to suggest better names than `YGDimensionFlexibility` & co.
Let me know if you prefet to kill the API without flexiblity specifier - I'll codemod everything then.

Summary: This is an update of facebook/yoga#368 which was reverted. It fixes support for align-content: strech with multiple lines. The problem with the last attempt at solving this was that align-items:stretch was interfering. We handle this now by detecting when the flex basis of the children hints at them overflowing. This is not 100% correct as the size of the items could change when remeasuring but it will work in 99% of cases.

Summary:
Currently, our configuration of Views looks like this:
```objc
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
view.yoga.isEnabled = YES;
view.yoga.height = 50;
view.yoga.width = 50;
```
Every time that we access `view.yoga` we have to access the associated object on `UIView` to get the `YGLayout`. This adds an extra `objc_msgSend` which increases binary size, and is slight perf impact.
This diff creates a way to modify the `YGLayout` with only a single `objc_msgSend`. Here's the new syntax:
```objc
UIView *view = [[UIView alloc] initWithFrame:CGRectZero];
[view configureLayoutWithBlock:^void(YGLayout *layout){
layout.isEnabled = YES
layout.height = 50;
layout.width = 50;
}];
```
Here's the Swift version:
```swift
let view = UIView(frame: .zero)
view.configureLayout { (layout) in
layout.isEnabled = true
layout.height = 50
layout.width = 50
}
```

Summary: While debugging something at Instagram, I kept seeing a UILabel be truncated when it clearly had enough room to display all its' text. What I realized is that during our pixel rounding, we were losing precision because we were using the incorrect rounding function for floats. Changing from `round()` (which is for doubles) to `roundf()` fixed it.

Summary:
Now that the Yoga library supports percentage values, the results returned from it's API were changed.
`YGNodeStyleGetPadding` returns the explicit value that you set, whereas `YGNodeLayoutGetPadding` returns the computed value. Since we are planning to build support for percentages, I'm modifying our API so that it strictly returns the value that was set. As a result:
```
view.yoga.margin = 10;
// view.yoga.margin == 10
// view.yoga.marginLeftWidth == 0
// view.yoga.marginRightWidth == 0
// etc.
