+ * 1.0 - Rafi Rubin ( Version From 2010-02-13 02:13:05)
+ * This cleans up the identification of multitouch
+ * groups and enables the end of group sync.
+ * Taps are now explicitly handled to adjust for the changes in the
+ * event stream in multitouch mode.
+ * Added triple and quad tap for the benefit of
+ * tools that recognize different tap types but
+ * do not have full multi touch support.
+ * 1.1 - N-trig - Add Change Log and defines of MTM firmware.
+ * Add debug Paramater change Driver name in hid_driver structure
