Closes #10

[AksharP5]

@StoneyJackson the ABC test issue should be resolved now, I have squashed and set a single commit, you can leave a comment with a better commit message and I will squash again if you do not agree with the one I have written, and this should be merged into main to fix the plcc testing issue when you clone languages. I have tested it using a PR in the plcc repo, which I have closed, and it worked as expected. This also fixes the issue of tests not being able to be ran when you are not located in the languages repo.

Added a second expected file to check against, as the ABC test can produce output in two different orders, but the issue should now be resolved, tested this feature branch in plcc and the tests passed, and they also pass in here.

[AksharP5]

Using 'git rev-parse --show-toplevel' to cd into root of languages repo, which allows for the second cd of each test to run properly without any errors when ran from anywhere, and I have tested this by cloning this repo into plcc and switching to this feature branch, and attempting to run tests from anywhere, and everything is functioning as expected.
