1. To build and run the project use:
stack build && stack exec pgc-exe <filepath>  +RTS -N4

2. To run the project so that threadscope can be used, use:
stack ghc -- -O2 -rtsopts -eventlog -threaded app/Main.hs && ./app/Main <filepath> +RTS -ls -N4
(The build command did not actually apply the -eventlog flag so I used ghc for this)

3. More tests can be found at
