[Eg6_analysis] user_ana on 64 bit machines

[Nathan Baltzell]

Dear EG6ers,

Here's an h10 comparison of this new 64bit-compiled cooking versus pass1v1.
The only significant differences I noticed are trigger time and neutral  
yields.

Similarities:
- same number of reconstructed events
- same number of good TPC tracks
- same number of IC clusters

Differences:  (only in CLAS)
- few-% more charged tracks for 64bit
- few-% more electrons and protons
- 40% more neutrons, but same number of gammas (!?)

Looking a little closer, event-by-event:
- trigger time is ALWAYS different (by hundreds of ps up to ~1 ns) (!?)
- beta for neutrals differs due to trigger time
- reconstructed SC time, EC energy, EC time, CC nphe are identical
- DC momentum is very similar (discrepancy is usually sub-MeV)
- reconstructed TPC and IC banks are practically identical

Note this is based on an early 1.2 GeV file, maybe we should check a 6 GeV  
run too.

Regards,
Nathan



P.S.   The files I compared are here:
