Add bash launcher

[e-caste]

Add launch.sh to add ability to:

• download original graph files from https://code.google.com/archive/p/grail/downloads (since we won't be able to upload many GBs of data to PoliTo's portal)
• generate Quer's benchmark graphs locally
• [optional] auto-run / select which graphs to run our algorithm implementation against

Bash is a prerequisite, but I think the professor will have no problem using it.

This seems to be a WSL only problem:

TODO: for the GRAIL DAGs, run the benchmark against the ones in the screenshot below (given by Quer) and hardcode or find a clever way to find the correspondance between a .gra and its .que file. Comment out unneeded downloads from DAGS.
