"""batch_runs.py will create multiple folders for simple_circuit model
runs with names like run_X where X goes from 1 to the number of jobs.

phase 1 the run_X folders are created and the programs and folders by
recursively copying simple_circuit into them.

phase 2 the num_of_columns.hoc and parameters.hoc files are created in
each run_x folder so that they are all ready to run with their
different assigned values.  A parameters[] list prepares the contents of
each of these files before they are written.

For now the following phases are external to this program:
initiated with
qsub run.pbs
and 
matlab
batch_polar_plots
or
batch_bi_polar_plots

phase 3 the mod files are compiled in each run_x folder and the jobs
are started by running build_net_Shep.hoc in each run_X folder These
jobs automatically save the tank and spike time data used to create
subsequent graphs

phase 4 the matlab tanks are created

phase 5 the tanks are analyzed to create and save matlab polar plot
figures

phase 6 the raster plots of spike activity are created and
saved.
