/**
 * Used for inter-object communication.
 * (Semi-)drop in replacement for Rik Schennink's Observer.
 *
 * Implementation differences:
 * - ES6
 * - The use of WeakMaps
 * - inform() and conceal() don't return a boolean indicating success.
 * - Subscription fn's are called with seperate arguments, instead of one data parameter. This is backwards compatible.
 *

/**
 * A single data store for modules to communicate with. Keeping 'the truth' in a single place reduces bugs and allows
 * for greater seperation of concerns.
 *
 * The module can be used as a singleton through DataStore.getSingleton('key'), or on instance basis through the new keyword.
 *
 * Uses the Observer module found here: https://gist.github.com/peeke/42a3f30c2a3856c65c224cc8a47b95f9
