Further Refinements

I'll look into the Feynman arrow addition mechanism and explain how that works in Pi-Space.  From an initial inspection, it looks like my pi-shell addition using law of the cosines.  However, in this case, we're dealing with "probability pi-shells".  Need some time to check out this further.  No fixed date for when but hopefully not too long...  Check out my work on Orbits for how I handled law of cosines and pi-shell addition previously in "local" space.
