 ### Updating
 
 * `componentWillReceiveProps(object nextProps)` is invoked when a mounted component receives new props. This method should be used to compare `this.props` and `nextProps` to perform state transitions using `this.setState()`.
 * `shouldComponentUpdate(object nextProps, object nextState): boolean` is invoked when a component decides whether any changes warrant an update to the DOM. Implement this as an optimization to compare `this.props` with `nextProps` and `this.state` with `nextState` and return false if React should skip updating.
 * `componentWillUpdate(object nextProps, object nextState)` is invoked immediately before updating occurs. You cannot call `this.setState()` here.

 * `getDOMNode(): DOMElement` can be invoked on any mounted component in order to obtain a reference to its rendered DOM node.
 * `forceUpdate()` can be invoked on any mounted component when you know that some deeper aspect of the component's state has changed without using `this.setState()`.
