+		   Dillip Kumar Kara for crossbar code.
+		   Zachary Lieberman for getting me into this stuff
+		   and for being so generous with time and code.
+		   The guys at Potion Design for helping me with VC++
+		   Josh Fisher for being a serious C++ nerd :)
+		   Golan Levin for helping me debug the strangest 
+		   and slowest bug in the world!
+		   
+		   And all the people using this library who send in 
+		   bugs, suggestions and improvements who keep me working on
