+ * as desired to be messaged, create a new Thread using the instance of this class created
+ * as the argument to the constructor, start the new Thread instance.<p>
+ *
+ * Also, this is intended to be used to message methods that either return void, or have
+ * a return which the developer using this class is uninterested in receiving.
