/**
* `Touchable`: Taps done right.
*
* You hook your `ResponderEventPlugin` events into `Touchable`. `Touchable`
* will measure time/geometry and tells you when to give feedback to the user.
*
* ====================== Touchable Tutorial ===============================
* The `Touchable` mixin helps you handle the "press" interaction. It analyzes
* the geometry of elements, and observes when another responder (scroll view
* etc) has stolen the touch lock. It notifies your component when it should
* give feedback to the user. (bouncing/highlighting/unhighlighting).
*
* - When a touch was activated (typically you highlight)
* - When a touch was deactivated (typically you unhighlight)
* - When a touch was "pressed" - a touch ended while still within the geometry
* of the element, and no other element (like scroller) has "stolen" touch
* lock ("responder") (Typically you bounce the element).
*
* A good tap interaction isn't as simple as you might think. There should be a
* slight delay before showing a highlight when starting a touch. If a
* subsequent touch move exceeds the boundary of the element, it should
* unhighlight, but if that same touch is brought back within the boundary, it
* should rehighlight again. A touch can move in and out of that boundary
* several times, each time toggling highlighting, but a "press" is only
* triggered if that touch ends while within the element's boundary and no
* scroller (or anything else) has stolen the lock on touches.
*
* To create a new type of component that handles interaction using the
* `Touchable` mixin, do the following:
*
* - Initialize the `Touchable` state.
*
* getInitialState: function() {
* return merge(this.touchableGetInitialState(), yourComponentState);
* }
*
* - Choose the rendered component who's touches should start the interactive
* sequence. On that rendered node, forward all `Touchable` responder
* handlers. You can choose any rendered node you like. Choose a node whose
* hit target you'd like to instigate the interaction sequence:
*
* // In render function:
* return (
* <View
* onStartShouldSetResponder={this.touchableHandleStartShouldSetResponder}
* onResponderTerminationRequest={this.touchableHandleResponderTerminationRequest}
* onResponderGrant={this.touchableHandleResponderGrant}
* onResponderMove={this.touchableHandleResponderMove}
* onResponderRelease={this.touchableHandleResponderRelease}
* onResponderTerminate={this.touchableHandleResponderTerminate}>
* <View>
* Even though the hit detection/interactions are triggered by the
* wrapping (typically larger) node, we usually end up implementing
* custom logic that highlights this inner one.
* </View>
* </View>
* );
*
* - You may set up your own handlers for each of these events, so long as you
* also invoke the `touchable*` handlers inside of your custom handler.
*
* - Implement the handlers on your component class in order to provide
* feedback to the user. See documentation for each of these class methods
* that you should implement.
*
* touchableHandlePress: function() {
* this.performBounceAnimation(); // or whatever you want to do.
* },
* touchableHandleActivePressIn: function() {
* this.beginHighlighting(...); // Whatever you like to convey activation
* },
* touchableHandleActivePressOut: function() {
* this.endHighlighting(...); // Whatever you like to convey deactivation
* },
*
* - There are more advanced methods you can implement (see documentation below):
* touchableGetHighlightDelayMS: function() {
* return 20;
* }
* // In practice, *always* use a predeclared constant (conserve memory).
* touchableGetPressRectOffset: function() {
* return {top: 20, left: 20, right: 20, bottom: 100};
* }

* ========== Geometry =========
* `Touchable` only assumes that there exists a `HitRect` node. The `PressRect`
* is an abstract box that is extended beyond the `HitRect`.
*
* +--------------------------+
* | | - "Start" events in `HitRect` cause `HitRect`
* | +--------------------+ | to become the responder.
* | | +--------------+ | | - `HitRect` is typically expanded around
* | | | | | | the `VisualRect`, but shifted downward.
* | | | VisualRect | | | - After pressing down, after some delay,
* | | | | | | and before letting up, the Visual React
* | | +--------------+ | | will become "active". This makes it eligible
* | | HitRect | | for being highlighted (so long as the
* | +--------------------+ | press remains in the `PressRect`).
* | PressRect o |
* +----------------------|---+
* Out Region |
* +-----+ This gap between the `HitRect` and
* `PressRect` allows a touch to move far away
* from the original hit rect, and remain
* highlighted, and eligible for a "Press".
* Customize this via
* `touchableGetPressRectOffset()`.

* A wrapper for making views respond properly to touches.

* The underlay comes from wrapping the child in a new View, which can affect

* for example if the backgroundColor of the wrapped view isn't explicitly set
* to an opaque color.
*
* TouchableHighlight must have one child (not zero or more than one).

* ```
* renderButton: function() {
