lots of patched code and files for EvoDemos Poster

most will be deleted later
Cleaned house after I created files for the EvoDemos Poster

I put the files re the Serengeti lions into a new folder "archive" to
be able to look at them later when we have the up-to-date data.
Mostly pushed forward the simulated data set (Hwange)

Made a new file "runModSim.R" that will run the model using the
simulated data set.
end of day upload. simulated data still not done.
