+ * Register a task for use within a buildfile.
+ * 
+ * This is for registering your own tasks -- or any non-core Task -- for use within a buildfile.
+ * If you find that you are using a particular class frequently, you may want to edit the 
+ * phing/tasks/defaults.properties file so that it is included by default. You may also
+ * want to submit it (if LGPL or compatible license) to be included in Phing distribution.

+ *   .
+ *   .
+ *   <mytag param1="val1" param2="val2"/>
+ * </pre>
+ * 
+ * TODO:
+ *    -- possibly refactor since this is almost the same as TypeDefTask
+ *      (right now these are just too simple to really justify creating an abstract class)
