 *
 *	This module implements a caller profile which is a group of information about a connected endpoint
 *	such as common caller id and other useful information such as ip address and destination number.
 *	A connected session's channel has up to 3 profiles: It's own, that of the session who spawned it
 *	and that of the session it has spawned.
 *
 *	In addition, this module implements an abstract interface for extensions and applications.
 *	A connected session's channel has one extension object which may have one or more applications
 *	linked into a stack which will be executed in order by the session's state machine when the 
 *	current state is CS_EXECUTE.
