[Halld-physics] kinematic fitter HowTo for eta-pi0 to 4 gamma

[Blake Leverington]

Hey all,

I added a wiki page which includes bits of my analysis program for doing 
a kinematic fit for eta-pi0 to 4gamma. Hopefully it's useful to someone, 
as I had a hard time finding any of this when I was trying to get it to 
work on my own.
