A multi-screen javascript Layout manager

 * An EventEmitter singleton that propagates events
 * across multiple windows. This is a little bit trickier since
 * windows are allowed to open childWindows in their own right
 *
 * This means that we deal with a tree of windows. Hence the rules for event propagation are:
 *
 * - Propagate events from this layout to both parents and children
 * - Propagate events from parent to this and children
 * - Propagate events from children to the other children (but not the emitting one) and the parent
