/**
 * The SelectMouseMode delegates handling of mouse events to the
 * listeners. This MouseMode type is ideal for Layers that want to
 * receive MouseEvents. The simplest way to set this up is for the
 * Layer to implement the MapMouseListener interface, and indicate
 * that it wants to receive events when the mouse mode is the
 * SelectMouseMode. Here's a code snippet for a Layer that would do
 * this: <code><pre>
 * public MapMouseListener getMapMouseListener() {
 *     return this;
 * }
 * 
 * public String[] getMouseModeServiceList() {
 *     return new String[] { SelectMouseMode.modeID };
 * }
 * </pre></code>
 * <p>
 * This class is functionally the same as the AbstractMouseMode,
 * except that it actually calls the fire methods in the
 * MapMouseSupport object to propagate the events.
