/**
 * 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);
 *     }
 *   });
 *
