* Summary of `ReactEventEmitter` event handling:
*
* - Top-level delegation is used to trap native browser events. We normalize
* and de-duplicate events to account for browser quirks.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.

/**
* `Transaction` creates a black box that is able to wrap any method such that
* certain invariants are maintained before and after the method is invoked
* (Even if an exception is thrown while invoking the wrapped method). Whoever
* instantiates a transaction can provide enforcers of the invariants at
* creation time. The `Transaction` class itself will supply one additional
* automatic invariant for you - the invariant that any transaction instance
* should not be ran while it is already being ran. You would typically create a
* single instance of a `Transaction` for reuse multiple times, that potentially
* is used to wrap several different methods. Wrappers are extremely simple -
* they only require implementing two methods.

* Bonus:
* - Reports timing metrics by method name and wrapper index.

* Use cases:
* - Preserving the input selection ranges before/after reconciliation.
* Restoring selection even in the event of an unexpected error.
* - Deactivating events while rearranging the DOM, preventing blurs/focuses,
* while guaranteeing that afterwards, the event system is reactivated.
* - Flushing a queue of collected DOM mutations to the main UI thread after a
* reconciliation takes place in a worker thread.
* - Invoking any collected `componentDidRender` callbacks after rendering new
* content.
* - (Future use case): Wrapping particular flushes of the `ReactWorker` queue
* to preserve the `scrollTop` (an automatic scroll aware DOM).
* - (Future use case): Layout calculations before and after DOM upates.
*
* Transactional plugin API:
* - A module that has an `initialize` method that returns any precomputation.
* - and a `close` method that accepts the precomputation. `close` is invoked
* when the wrapped process is completed, or has failed.
