-    This example shows how to use the new callback system. In the old system
-    Mbed's FunctionPointer[1] type was used to store abd make calls to callbacks.
-    However, that limits the callback function prototype to void func(void);
-    which means we cannot pass parameters.
-    
-    This latest version of MODSERIAL now uses its own callback object. This allows
-    the passing of a pointer to a class that holds information about the MODSERIAL
-    object making the callback. As of version 1.18 one critcal piece of information
-    is passed, a pointer to the MODSERIAL object. This allows callbacks to use the
-    MODSERIAL functions and data.
-        
-    Additionally, since MODSERIAL and the callback parameter class MODSERIAL_IRQ_INFO
-    are friends, MODSERIAL_IRQ_INFO can access the protected functions of MODSERIAL.
-    This is used to ensure functions that can only be called during a callback
-    can be invoked from a callback.
