 Routine Description:

	The constructor.

 Arguments:
	
	AllocRtnName	- The allocator rtn name.
	FreeRtnName		- Free rtn name
	InterfaceName	- interface name without any mangling.
	RundownRtnName	- The context handle rundown in case necessary.

 Return Value:
	
	NA

 Notes:

	Make an entry into the dictionary if it does not exist.
