# To add a new validation method (aka "plugin"):
#   1) Add its name to the PLUGIN_LIST below
#   2) Invoke "add_test_type" with it below
#   3) Add a "<plugin>_filefilter" function to decide whether the plugin needs to be run based on changed files
#   4) Add a "<plugin>_rebuild" function to call out to ant to perform the validation method.
# See examples of the above-described function types ^^ below.
   
# Both compile+javac plugins are required, as well as unit+junit: in both cases, neither work individually
