[G12] Kin. Fit and mom. corrections

[Michael C. Kunkel]

Greetings Andrea,

Line 339
//event.g12Pcor();  //Momentum corrections....
Would invoke the CLASEvent version of momentum correction, which were 
never verified or used by anyone in G12.
We have a separate package for momentum corrections, which is basically 
a correction in phi.
However, if memory serves me correct, these corrections should not be 
used if using the Fitter, because the fitter handles the phi correction.

Maybe Daniel can remind us if my memory on this subject is faulty.
