Updated README file
Uploaded my most recent stable version of TSM code

This is the version that I used in my 2012 paper that I first submitted to ApJ and arXiv:
http://adsabs.harvard.edu/abs/2012arXiv1210.0014D

I now have plans to change the name from TSM_v11 to MCMAC, since Monte Carlo
Merging Analysis Code is a bit more appropriate than Time Since Merger.
Changed name of TSM code to MCMAC

I chose to do this because I think that Monte Carlo Merger Analysis Code
is more appropriate than Time Since Merger.
Corrected version number in header
Renamed MCMCengine function to MCengine

This is more appropriate since it is really just a Monte Carlo analysis
and not a Markov Chain Monte Carlo analysis.  The MCMC function name
was a vestige of a previous program I had written.
