## Observer.js
/**
 * 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.
