Done for MSM.

Thanks Eric. Unfortunately, the compile-time went up after the change
for VC. Not much but up. Example, CompositeTutorialEuml.
Now: 57s (ignoring a first compile of 77s, statistical VC error)
g++ 4.4: Roughly the same time (21s / 21.7). Yes, much faster than VC, I know...
I suppose what I gain from preprocessing is lost from moving arity from 7 to 10.
It's not a big change but from previous burns, I know that the
slightest increase is enough to get some working code crash a VC
compiler at a user's machine, so I would not welcome another increase.
Thanks for the hard work anyway, I'm happy to get rid of my #define's.
