Options for wrappers

[vsoch]

I'm struggling with editing snakemake/wrappers.py because I don't understand all the options - the default seems to be to specify the subfolder in the GitHub repository here, but that wouldn't make sense to have the testing files use it (unless they are merged to master) because we would always be testing the master branch. I was testing a local wrapper with a file://../wrapper.py (up one folder from the test Snakemake file) but that doesn't seem to work. It looks like it could also be specified as http: or file: or git+file: and I'm hoping someone can help me to clearly lay out how this is supposed to work so I can do the implementation (the current one doesn't work / make sense to me). Thanks!

okay I'm going to try something that will just "make it work" and someone that knows what is going on can review :P
