#This is a simple test script to run the translator across all files in the directory in which it is run.
#Useage is:
#    $ perl Test.pl [PATH]
#to run a compiled version stored at PATH (which is optional). It can also be run as
#    $ perl Test.pl -i [PATH]
#which runs ghc seperately for each test. This option is very slow, but it is useful when the code does not compile (such as on Intel Macs without special consideration).
