clarify license

[maxheld83]

qmethod is currently GPL licensed, as per DESCRIPTION

License: GPL (>= 2)

I just read here:

For now, I’d suggest choosing between the GPL-3 (the GNU Public License v3) and MIT licenses. GPL-3 has a “pass-through” provision: software that incorporates GPL-3 code must also be licensed as GPL-3. This is a good but restrictive thing. The MIT license is the most bare-bones license possible: it basically just says “Do what you want, but don’t blame me.”

I don't have a clue about licensing, just wanted to bring this up: does GPL work for what you intend or might the pass-through be a problem @aiorazabala?

nevermind, I missunderstood the pass-through thing; it seems to affect usage of qmethod by others, not vice versa.
Sorry about the confusion.
I added the GPL 2.0 licence to the repo, just for the sake of completeness.
