Added 2 new scripts that provide a harness for regression testing. plt.sh is a script that goes through the full pipeline of converting plt code into java and compiling the java code. It also provides options for running the java code generated, and cleaning out the *.java and *.class that were generated; consult the ReadMe_Testing.txt for details as to how to invoke it. regress.sh is a script that makes use of plt.sh to perform regression testing, and provide a summary report of passes and failures along with several other debugging details. Again consult ReadMe_Testing.txt for details. Modified Makefile to no longer include Ounit references (commented them out).
