Ignoring Multinest
Removing extra white space.
Clean up code

Removed old out-commented code originally put in place to test the use
of multiprocessing for adding stuff to the database.

It didn't work, and will need a complete rework if it is to be used
in the future.
Add extra step to README

This steps tells how to calculate the position angle of member
galaxies within an association.
Rename file containing science calls and plotting
Add missing plt.show()
Plot member pos angle vs diff in deV pos angles

The current state of the science script now correctly plots
a 2-d histogram with the position angle in the cluster of member
galaxies on one axis and the difference in the intrinsic position angles
of the BCG and member galaxy taken from De Vaucouleur photometry
in SDSS.
