Added testing! call kraken like so ./kraken --test ../path/to/test/name_of_test_without_extention This will make kraken compile and run name_of_test_without_extention.krak and compare the output it generates on stdout to name_of_test_without_extention.expected_results. If they pass, then it records the pass, if not, it records the failure and saves the intermediate files generated. It has revealed some bugs which I will fix in upcoming commits.
