Multiple-universe histograms based on ROOT.

There is an environment-setting script in the home area that looks for a ROOT configuration script in the user $HOME area. If it doesn't find it, it complains. If it gets past this, it adds the RooMUHistos library directories to the $LD_LIBRARY_PATH or $DYLD_LIBRARY_PATH depending on OS.

Once the environment is configured, run make in the PlotUtils directory and then run make in the macros directory. Then test the build with macros/tryToRead and macros/tryToWrite.
