+/**
+ * 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':
+ * case 'city-update':
+ * flightDispatcher.waitFor([CityStore.dispatchToken]);
+ * FlightPriceStore.price =
+ * getFlightPriceStore(CountryStore.country, CityStore.city);
+ * break;
+ * }
+ * });
+ *
+ * The `country-update` payload will be guaranteed to invoke the stores'
+ * registered callbacks in order: `CountryStore`, `CityStore`, then
+ * `FlightPriceStore`.

+ * An extension of the "same-value" algorithm as [described for use by ES6 Map
+ * and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
+ *
+ * NaN is considered the same as NaN, however -0 and 0 are considered the same
+ * value, which is different from the algorithm described by
+ * [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
+ *
+ * This is extended further to allow Objects to describe the values they
+ * represent, by way of `valueOf` or `equals` (and `hashCode`).
+ *
+ * Note: because of this extension, the key equality of Immutable.Map and the
+ * value equality of Immutable.Set will differ from ES6 Map and Set.
+ *
+ * ### Defining custom values
+ *
+ * The easiest way to describe the value an object represents is by implementing
+ * `valueOf`. For example, `Date` represents a value by returning a unix
+ * timestamp for `valueOf`:
+ *
+ * var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
+ * var date2 = new Date(1234567890000);
+ * date1.valueOf(); // 1234567890000
+ * assert( date1 !== date2 );
+ * assert( Immutable.is( date1, date2 ) );
+ *
+ * Note: overriding `valueOf` may have other implications if you use this object
+ * where JavaScript expects a primitive, such as implicit string coercion.
+ *
+ * For more complex types, especially collections, implementing `valueOf` may
+ * not be performant. An alternative is to implement `equals` and `hashCode`.
+ *
+ * `equals` takes another object, presumably of similar type, and returns true
+ * if the it is equal. Equality is symmetrical, so the same result should be
+ * returned if this and the argument are flipped.
+ *
+ * assert( a.equals(b) === b.equals(a) );
+ *
+ * `hashCode` returns a 32bit integer number representing the object which will
+ * be used to determine how to store the value object in a Map or Set. You must
+ * provide both or neither methods, one must not exist without the other.
+ *
+ * Also, an important relationship between these methods must be upheld: if two
+ * values are equal, they *must* return the same hashCode. If the values are not
+ * equal, they might have the same hashCode; this is called a hash collision,
+ * and while undesirable for performance reasons, it is acceptable.
+ *
+ * if (a.equals(b)) {
+ * assert( a.hashCode() === b.hashCode() );
+ * }
+ *
+ * All Immutable collections implement `equals` and `hashCode`.
+ *
