@jlamy I completely replaced the previous Provider Directory section with portions of the mCSD whitepaper and Topologies whitepaper. I really need you to help refine this. I might have pulled the right stuff, I might have not. There might be a better drawing, but I grabbed one simply because I think a drawing would be helpful. The intent is not to replace those whitepapers, but rather to inspire the reader of the HIE whitepaper to go read these others.

I read through this and think it is ready to move forward. I ddi not have really anything to add to the directory section.
