Testing

Preliminary beginnings of adding unit testing to burlap. 

Two ways to run, from the command line:
set $JAVA_HOME_6, $JAVA_HOME_7, $JAVA_HOME_8 to their respective jvm home locations. You can just point two or all three variables to the same JAVA_HOME if you don't have all three jvms to test.
run 'ant test'

From Eclipse:
add testing as a src folder in the configure build_path menu.
Run TestRunner.java
