+/// Base definition for an LED controller.  Pretty much the methods that every LED controller object will make available.  
+/// Note that the showARGB method is not impelemented for all controllers yet.   Note also the methods for eventual checking
+/// of background writing of data (I'm looking at you, teensy 3.0 DMA controller!).  If you want to pass LED controllers around
+/// to methods, make them references to this type, keeps your code saner.
 class CLEDController { 
 public:
 	// initialize the LED controller
