+/**
+ *
+ * Responder System:
+ * ----------------
+ *
+ * - A global, solitary "interaction lock" on a view.
+ * - If a node becomes the responder, it should convey visual feedback
+ *   immediately to indicate so, either by highlighting or moving accordingly.
+ * - To be the responder means, that touches are exclusively important to that
+ *   responder view, and no other view.
+ * - While touches are still occurring, the responder lock can be transferred to
+ *   a new view, but only to increasingly "higher" views (meaning ancestors of
+ *   the current responder).
+ *
+ * Responder being granted:
+ * ------------------------
+ *
+ * - Touch starts, moves, and scrolls can cause an ID to become the responder.
+ * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
+ *   the "appropriate place".
+ * - If nothing is currently the responder, the "appropriate place" is the
+ *   initiating event's `targetID`.
+ * - If something *is* already the responder, the "appropriate place" is the
+ *   first common ancestor of the event target and the current `responderInst`.
+ * - Some negotiation happens: See the timing diagram below.
+ * - Scrolled views automatically become responder. The reasoning is that a
+ *   platform scroll view that isn't built on top of the responder system has
+ *   began scrolling, and the active responder must now be notified that the
+ *   interaction is no longer locked to it - the system has taken over.
+ *
+ * - Responder being released:
+ *   As soon as no more touches that *started* inside of descendants of the
+ *   *current* responderInst, an `onResponderRelease` event is dispatched to the
+ *   current responder, and the responder lock is released.
+ *
+ * TODO:
+ * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
+ *   determines if the responder lock should remain.
+ * - If a view shouldn't "remain" the responder, any active touches should by
+ *   default be considered "dead" and do not influence future negotiations or
+ *   bubble paths. It should be as if those touches do not exist.
+ * -- For multitouch: Usually a translate-z will choose to "remain" responder
+ *  after one out of many touches ended. For translate-y, usually the view
+ *  doesn't wish to "remain" responder after one of many touches end.
+ * - Consider building this on top of a `stopPropagation` model similar to
+ *   `W3C` events.
+ * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
+ *   not `onResponderTerminationRequest` returns `true` or `false`.

+/**
+ * A note about event ordering in the `EventPluginHub`.
+ *
+ * Suppose plugins are injected in the following order:
+ *
+ * `[R, S, C]`
+ *
+ * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
+ * `onClick` etc) and `R` is `ResponderEventPlugin`.
+ *
+ * "Deferred-Dispatched Events":
+ *
+ * - The current event plugin system will traverse the list of injected plugins,
+ *   in order, and extract events by collecting the plugin's return value of
+ *   `extractEvents()`.
+ * - These events that are returned from `extractEvents` are "deferred
+ *   dispatched events".
+ * - When returned from `extractEvents`, deferred-dispatched events contain an
+ *   "accumulation" of deferred dispatches.
+ * - These deferred dispatches are accumulated/collected before they are
+ *   returned, but processed at a later time by the `EventPluginHub` (hence the
+ *   name deferred).
+ *
+ * In the process of returning their deferred-dispatched events, event plugins
+ * themselves can dispatch events on-demand without returning them from
+ * `extractEvents`. Plugins might want to do this, so that they can use event
+ * dispatching as a tool that helps them decide which events should be extracted
+ * in the first place.
+ *
+ * "On-Demand-Dispatched Events":
+ *
+ * - On-demand-dispatched events are not returned from `extractEvents`.
+ * - On-demand-dispatched events are dispatched during the process of returning
+ *   the deferred-dispatched events.
+ * - They should not have side effects.
+ * - They should be avoided, and/or eventually be replaced with another
+ *   abstraction that allows event plugins to perform multiple "rounds" of event
+ *   extraction.
+ *
+ * Therefore, the sequence of event dispatches becomes:
+ *
+ * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
+ * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
+ * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
+ * - `R`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `S`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ * - `C`s extracted events (if any)   (dispatched by `EventPluginHub`)
+ *
+ * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
+ * on-demand dispatch returns `true` (and some other details are satisfied) the
+ * `onResponderGrant` deferred dispatched event is returned from
+ * `extractEvents`. The sequence of dispatch executions in this case
+ * will appear as follows:
+ *
+ * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
+ * - `touchStartCapture`       (`EventPluginHub` dispatches as usual)
+ * - `touchStart`              (`EventPluginHub` dispatches as usual)
+ * - `responderGrant/Reject`   (`EventPluginHub` dispatches as usual)
