ir_protocol.h

/*ir_protocol.h
Defines classes and constants that describe IR signalling protocols.

NOTE:
	-*Implementation of what is provided in ir_packet.h*
	-Should be limited to actually describing protocols themselves
	 (not generic structures & constants).
	-Used directly by IRMsg in the ir_message module.
