[d2n-analysis-talk] Analyzer output: histograms written to ROOT files

[Diana Parno]

Thanks, Brad! It's running now. I wound up linking my replay script to 
yours, but I had trouble when I tried to point my environment variables to 
your copy of the analyzer using the root-setup.sh script.

Once I was pointing to your copy ($ANALYZER = 
/home/brads/d2n_analysis_copy/analyzer), I received an error message when 
I tried to run the analyzer (by typing "analyzer" on the command line):

analyzer: error while loading shared libraries: libCore.so.5.18: cannot 
open shared object file: No such file or directory

I then changed around my library links to point to yours, but when the 
analyzer environment opened and tried to load the libraries, there were 
some more error messages:

Error in <TUnixSystem::Load>: version mismatch, 
/home/dseymour/onlana/./libBigBite.so = 51800, ROOT = 52200
rootlogon.C: Loading BigBite Library...
Error in <TUnixSystem::Load>: version mismatch, 
/home/dseymour/onlana/./libBBNormAna.so = 51800, ROOT = 52200

To make things even more exciting, it segfaulted when I tried to quit via 
.q!

I'm now using Dave's version of the analyzer and your version of 
replay_det_BB.C, which at least seems to run (though not lightning-fast; 
hard to tell if there's a speed change). No evidence of housecleaning yet.
