	6	OpProgress - Operation Progress
	7
	8	This class allows lengthy operations to communicate their progress
	9	to the GUI. The progress model is simple and is not designed to handle
	10	the complex case of the multi-activity aquire class.
	11
	12	The model is based on the concept of an overall operation consisting
	13	of a series of small sub operations. Each sub operation has it's own
	14	completion status and the overall operation has it's completion status.
	15	The units of the two are not mixed and are completely independent.
	16
	17	The UI is expected to subclass this to provide the visuals to the user.
