+ * DESCRIPTION:
+ * The device change listener to be used by the whole MOTODEV Studio for Android
+ * tool. Other plugins should not register listeners in DDMS. Instead, use 
+ * DDMSFacade
+ *
+ * RESPONSIBILITY:
+ * Delegate the deviceConnected and deviceDisconnected events to the registered
+ * runnables
+ *
+ * COLABORATORS:
+ * None. 
+ *
+ * USAGE:
+ * This class shall be used by DDMS and DDMSFacade only
