//## Class: C_PGC
//	Implements the DVD Program Chain play-back control (DVD
//	4.3).
//
//	Implements a simple state machine which decodes the PGC
//	information into a sequence of action items for the
//	caller. It handles:
//	- stream selection
//	- random/shuffle/loop play-back
//	- program selection
//	- cell selection (including angle block processing based
//	on SPRM(3))
//	- command selection
//	- execution of intra-PGC commands (GoTo group, LinkCN,
//	etc)
//	Action items are one of the:
//	- select stream
//	- execute command
//	- play cell
//	- pause
//	- terminate
//
//	It also provides direct access to PGC info through the
//	public member classes.
