Command line interface for SINGE

[agitter]

We would like to have a script that shows how to run SCINGE from the command line. It will provide all of the input data files and GLG hyperparmeters. A demo script will reproduce the test run in SCINGE_Example.m.

Initially this will assume that all GLG runs are done locally. We can parallelize the GLG runs for high-thoughput computing (#6) as a later step.
