Update to StGammaMaker code to improve reproducability

Updated on Sat, 2008-07-05 08:49 by testadmin. Originally created by jwebb on 2008-06-30 16:33.
Abstract: The offline/StGammaMaker is normally compiled w/in the DEV framework, since we rely on trigger and other makers which do not necessarily live in a stable library. We need a mechanism to track which codes were run for a particular gamma-tree production. We implement the following.
1. A new class, StGammaTreeVersion, will contain CVS version information for each maker in the chain, and each storage container (StGammaCandidate, StGammaTower, etc...) used during tree generation
2. This information will be output to the logfile
3. This information will also be saved to the root file which contains the TTree.

The following is an excerpt from the log file, but can also be obtained by the following commands:
$ root loadGammaLibs.C file-containing-gamma-tree.root
root [0] version->print();
StQAInfo: -- StGammaMaker versioning information follows --
-- List of makers --

It should be straightforward to modify StGammaVersion so that it can verify that two different root files are from a compatible production (i.e. all of the CVS version numbers agree.
