+General Description:
+This module implements a function for debug logs on the serial line of the
+AVR microcontroller. Debugging can be configured with the define
+'DEBUG_LEVEL'. If this macro is not defined or defined to 0, all debugging
+calls are no-ops. If it is 1, DBG1 logs will appear, but not DBG2. If it is
+2, DBG1 and DBG2 logs will be printed.
+
+A debug log consists of a label ('prefix') to indicate which debug log created
+the output and a memory block to dump in hex ('data' and 'len').
