/**
 * Layers Control
 *
 * This directive is used to configure the layers control. The input accepts an object with two
 * key-value maps of layer name -> layer. Mutable changes are detected. On changes, a differ is
 * used to determine what changed so that layers are appropriately added or removed.
 *
 * To specify which layer to show as the 'active' baselayer, you will want to add it to the map
 * using the layers directive. Otherwise, the last one it sees will be used.
