	initialize a buffer to start at a given address and have given size
unsigned char	bufferGetFromFront (cBuffer *buffer)
	get the first byte from the front of the buffer
void	bufferDumpFromFront (cBuffer *buffer, unsigned short numbytes)
	dump (discard) the first numbytes from the front of the buffer
unsigned char	bufferGetAtIndex (cBuffer *buffer, unsigned short index)
	get a byte at the specified index in the buffer (kind of like array access)
