/**
 * @fileoverview This file provides the layer manager directive. That directive
 * is used to create the list of selected layers in the page.
 *
 * Example:
 *
 * <app-layermanager app-layermanager-map="::mainCtrl.map"
 *     app-layermanager-layers="::mainCtrl.selectedLayers">
 * </app-layermanager>
 *
 * Note the use of the one-time binding operator (::) in the map and layers
 * expressions. One-time binding is used because we know the map and the array
 * of layers are not going to change during the lifetime of the application.
 * The content of the array of layers may change, but not the array itself.
