Mine Model DPM Rev 3

Partial review. There is a bug I (we) need to resolve. I don't think the
Resources are working right to control the "activity" of the ROM
sources. I've added a test Resource (lower left) in the red box.
Mine Model DPM Rev 9

Reviewed all system logic based on the functional specification, which
is in the Quality Management Plan. For train load out, added monitors
for TLO bin emptied, coal quality "current" and "next" which should be
added to the train interface logic. Made the definitions that LA = 0, HA
= 1 and empty queue and TLO = -1. Blending should be easier with these
definitions.
Will add more documentation in next rev.
Updated with notes and description of changes

I still need to go through and document the logic, added descriptors
within the model.
Small fixed from Rev 10

Addresses and confirms many of the comments from Paul's email of 10 Feb
