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:
This supersedes #309 and #305.
This is still a **work-in-progress.**
**TODO**
- [x] Create Xcode project that builds an iOS framework
- [x] Fix failing tests on Xcode
- [ ] Make `pod lib lint` pass and make sure YogaKit can be included using CocoaPods
- [ ] Add `pod lib lint` to .travis.yml
- [x] Migrate to travis osx image with Xcode 8.2
**FOLLOW-UP**
- [ ] Make YogaKitSample use framework built by new Xcode project.
- [ ] Make Travis to upload prebuilt versions of the framework. More [here](https://github.com/Carthage/Carthage#use-travis-ci-to-upload-your-tagged-prebuild-frameworks)
- [ ] Upgrade github/jekyll docs about installation using Cocoapods/Carthage
