/**
 * Dispatcher is used to broadcast payloads to registered callbacks. This is
 * different from generic pub-sub systems in two ways:
 *
 *   1) Callbacks are not subscribed to particular events. Every payload is
 *      dispatched to every registered callback.
 *   2) Callbacks can be deferred in whole or part until other callbacks have
 *      been executed.
 *
 * For example, consider this hypothetical flight destination form, which
 * selects a default city when a country is selected:
 *
 *   var flightDispatcher = new Dispatcher();
 *
 *   // Keeps track of which country is selected
 *   var CountryStore = {country: null};
 *
 *   // Keeps track of which city is selected
 *   var CityStore = {city: null};
 *
 *   // Keeps track of the base flight price of the selected city
 *   var FlightPriceStore = {price: null}
 *
 * When a user changes the selected city, we dispatch the payload:
 *
 *   flightDispatcher.dispatch({
 *     actionType: 'city-update',
 *     selectedCity: 'paris'
 *   });
 *
 * This payload is digested by `CityStore`:
 *
 *   flightDispatcher.register(function(payload) {
 *     if (payload.actionType === 'city-update') {
 *       CityStore.city = payload.selectedCity;
 *     }
 *   });
 *
 * When the user selects a country, we dispatch the payload:
 *
 *   flightDispatcher.dispatch({
 *     actionType: 'country-update',
 *     selectedCountry: 'australia'
 *   });
 *
 * This payload is digested by both stores:
 *
 *    CountryStore.dispatchToken = flightDispatcher.register(function(payload) {
 *     if (payload.actionType === 'country-update') {
 *       CountryStore.country = payload.selectedCountry;
 *     }
 *   });
 *
 * When the callback to update `CountryStore` is registered, we save a reference
 * to the returned token. Using this token with `waitFor()`, we can guarantee
 * that `CountryStore` is updated before the callback that updates `CityStore`
 * needs to query its data.
 *
 *   CityStore.dispatchToken = flightDispatcher.register(function(payload) {
 *     if (payload.actionType === 'country-update') {
 *       // `CountryStore.country` may not be updated.
 *       flightDispatcher.waitFor([CountryStore.dispatchToken]);
 *       // `CountryStore.country` is now guaranteed to be updated.
 *
 *       // Select the default city for the new country
 *       CityStore.city = getDefaultCityForCountry(CountryStore.country);
 *     }
 *   });
 *
 * The usage of `waitFor()` can be chained, for example:
 *
 *   FlightPriceStore.dispatchToken =
 *     flightDispatcher.register(function(payload) {
 *       switch (payload.actionType) {
 *         case 'country-update':
 *           flightDispatcher.waitFor([CityStore.dispatchToken]);
 *           FlightPriceStore.price =
 *             getFlightPriceStore(CountryStore.country, CityStore.city);
 *           break;
 *
 *         case 'city-update':
 *           FlightPriceStore.price =
 *             FlightPriceStore(CountryStore.country, CityStore.city);
 *           break;
 *     }
 *   });
 *
 * The `country-update` payload will be guaranteed to invoke the stores'
 * registered callbacks in order: `CountryStore`, `CityStore`, then
 * `FlightPriceStore`.

/**
 * Summary of `ReactBrowserEventEmitter` event handling:
 *
 *  - Top-level delegation is used to trap most native browser events. This
 *    may only occur in the main thread and is the responsibility of
 *    ReactEventListener, which is injected and can therefore support pluggable
 *    event sources. This is the only work that occurs in the main thread.
 *
 *  - We normalize and de-duplicate events to account for browser quirks. This
 *    may be done in the worker thread.
 *
 *  - 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.

 * automatic invariant for you - the invariant that any transaction instance

 * single instance of a `Transaction` for reuse multiple times, that potentially
 * is used to wrap several different methods. Wrappers are extremely simple -

 * 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 `componentDidUpdate` 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 updates.
 *
 * 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.

//	1. Enforce API surface and semantic compatibility with 1.9.x branch

//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

     * Creates a `lodash` object which wraps `value` to enable implicit chaining.
     * Methods that operate on and return arrays, collections, and functions can
     * be chained together. Methods that return a boolean or single value will
     * automatically end the chain returning the unwrapped value. Explicit chaining
     * may be enabled using `_.chain`. The execution of chained methods is lazy,
     * that is, execution is deferred until `_#value` is implicitly or explicitly
     * called.
     *
     * Lazy evaluation allows several methods to support shortcut fusion. Shortcut
     * fusion is an optimization that merges iteratees to avoid creating intermediate
     * arrays and reduce the number of iteratee executions.
     *
     * Chaining is supported in custom builds as long as the `_#value` method is
     * directly or indirectly included in the build.
     *
     * In addition to lodash methods, wrappers have `Array` and `String` methods.
     *
     * The wrapper `Array` methods are:
     * `concat`, `join`, `pop`, `push`, `reverse`, `shift`, `slice`, `sort`,
     * `splice`, and `unshift`
     *
     * The wrapper `String` methods are:
     * `replace` and `split`
     *
     * The wrapper methods that support shortcut fusion are:
     * `compact`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `filter`,
     * `first`, `initial`, `last`, `map`, `pluck`, `reject`, `rest`, `reverse`,
     * `slice`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `toArray`,
     * and `where`
     *
     * The chainable wrapper methods are:
     * `after`, `ary`, `assign`, `at`, `before`, `bind`, `bindAll`, `bindKey`,
     * `callback`, `chain`, `chunk`, `commit`, `compact`, `concat`, `constant`,
     * `countBy`, `create`, `curry`, `debounce`, `defaults`, `defer`, `delay`,
     * `difference`, `drop`, `dropRight`, `dropRightWhile`, `dropWhile`, `fill`,
     * `filter`, `flatten`, `flattenDeep`, `flow`, `flowRight`, `forEach`,
     * `forEachRight`, `forIn`, `forInRight`, `forOwn`, `forOwnRight`, `functions`,
     * `groupBy`, `indexBy`, `initial`, `intersection`, `invert`, `invoke`, `keys`,
     * `keysIn`, `map`, `mapValues`, `matches`, `matchesProperty`, `memoize`, `merge`,
     * `mixin`, `negate`, `noop`, `omit`, `once`, `pairs`, `partial`, `partialRight`,
     * `partition`, `pick`, `plant`, `pluck`, `property`, `propertyOf`, `pull`,
     * `pullAt`, `push`, `range`, `rearg`, `reject`, `remove`, `rest`, `reverse`,
     * `shuffle`, `slice`, `sort`, `sortBy`, `sortByAll`, `sortByOrder`, `splice`,
     * `spread`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, `tap`,
     * `throttle`, `thru`, `times`, `toArray`, `toPlainObject`, `transform`,
     * `union`, `uniq`, `unshift`, `unzip`, `values`, `valuesIn`, `where`,
     * `without`, `wrap`, `xor`, `zip`, and `zipObject`
     *
     * The wrapper methods that are **not** chainable by default are:
     * `add`, `attempt`, `camelCase`, `capitalize`, `clone`, `cloneDeep`, `deburr`,
     * `endsWith`, `escape`, `escapeRegExp`, `every`, `find`, `findIndex`, `findKey`,
     * `findLast`, `findLastIndex`, `findLastKey`, `findWhere`, `first`, `has`,
     * `identity`, `includes`, `indexOf`, `inRange`, `isArguments`, `isArray`,
     * `isBoolean`, `isDate`, `isElement`, `isEmpty`, `isEqual`, `isError`,
     * `isFinite`,`isFunction`, `isMatch`, `isNative`, `isNaN`, `isNull`, `isNumber`,
     * `isObject`, `isPlainObject`, `isRegExp`, `isString`, `isUndefined`,
     * `isTypedArray`, `join`, `kebabCase`, `last`, `lastIndexOf`, `max`, `min`,
