Kstar

Made the following adjustments to KSTAR configuration:
-create_network_pickles() will only generate new pickles if it does not find them in the network directory
-config.PROCESSES was removed. Instead of setting config variable, the number of processes to run in parallel is set through function parameters.

Configuration files updated so that source code does not require editing and all setup can easily be performed within python

The first release of the KSTAR algorithm intended for public use. The core algorithm is stable (pruning, mapping, activity calculation, and plotting), but there will be upcoming updates to the package which will improve the ability to dig deeper into the activity predictions and their meaning, if desired.
