Create generate.py

This example takes the demonstration of how to create the 17 segment model for the left
ventricle recommended by the American Heart Association (AHA) 
found here  https://github.com/curiale/matplotlib/blob/master/examples/pylab_examples/leftventricle_bulleye.py.
and expands it to allow a list of data rows, divided into groups, to be read in. Expects the following format 
in CSV file:
 - First row ignored (header)
 - First column ignored (ID)
 - Second column used to define group (each group generates own matplotlib display)
 - Then next 17 columns represent a value in a range 1 - 12 representing a figure for that area of the left ventricle
 
 Last graph in each group represents the mean of values for that group
