Update tutorial.md to improve grammatical parallelism in features list. Also added periods to follow first item's syntax.
BEFORE: "Live updates: as other users comment we'll pop them into the comment view in real time"
AFTER: "Live updates: other users' comments are popped into the comment view in real time."
BEFORE: "Markdown formatting: users can use Markdown to format their text"
AFTER: "Markdown formatting: users can use Markdown to format their text."
Based on conversation in https://github.com/facebook/react/pull/2501. A good place to guide people further in finding the complete set of tools needed to build an application.
Update to the animation documentation for ReactTransitionGroup to clear the air on where one can use it.
If someone tries to use it off of React.addons.ReactTransitionGroup, which is undefined, instead of its real location, React.addons.TransitionGroup, they get a vague error about being unable to set defaultProps of undefined in the React createElement body.
The word "Friends" does establish a relationship however it does not fit in the vernacular of react.
This change makes the phrase more explicit and more familiar.
ReactTextComponent's implementation is DOM-specific; instead of flattenChildren creating the ReactTextComponent instances, ReactNativeComponent now takes care of having ReactTextComponent injected and creating the component instance. I also renamed ReactTextComponent to ReactDOMTextComponent and moved it to browser/ui/ where it belongs. ReactDOMTextComponent no longer inherits directly from ReactComponent and instead implements construct and {mount,receive,unmount}Component directly.
This diff removes `ReactTestUtils.isTextComponent` which should have previously never returned true when using public APIs.
Test Plan: jest, use ballmer-peak example.
