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