(Nearly) Ready to test with your *.in.* files

'hist_plotting.m' makes a *.in.* file and is ready to run brainsearch.py; be sure to set the opttype at the beginning of hist_plotting

Questions:
1. How do you want to name the param_file that brainsearch.py reads in?
2. How do you want to name the output?
3. It needs to be run in your directory so that it finds the correct *.in.* files
