[g13] momentum corrections complete

[Paul Mattione]

The momentum corrections have been finished, and have been stored in  
cvs in the packages/utilities/decayutils package.  The procedure and  
plots can be found at:

http://clasweb.jlab.org/rungroups/g13/wiki_secure/index.php/MomentumCorrections

and the instructions for using them are in cvs: packages/utilities/ 
decayutils/README_FIRST.txt

I'll now begin performing the beam energy corrections.  Please let me  
know if you have any questions.
