Setup MASON in an SBT project
#!/bin/bash -v
# MASON (http://cs.gmu.edu/~eclab/projects/mason/) has no MAVEN repository, and
# is built with Makefiles. Sinec I build MASON simulations in Scala with SBT,
# this is inconvienent. This script downloads the latest version of MASON and
# its listed dependencies, and places them in the lib directory. I've never been
# very clear on licensing issues, so I hope I'm not in violation (and I hope
# I'm not stepping on anyone's toes.) If I am, please let me know.

# The most convienent way to run is to CD into your scripts base directory and
