What license should this repo have?

[jessegreenberg]

On slack chat I said

From the code review checklist: Is the LICENSE file correct? (GPL v3 for sims, MIT for common code)

inverse-square-law-common is shared by gravity-force-lab, gravity-force-lab-basics, and coulombs-law, implementing much of the model and view for all three sims.
Is this "common" and should it have an MIT license?

I do not know enough to say. Currently has GPL v3, but might need a new license if it requires MIT.

For #30.

If I recall correctly, it is only “common” enough to support a few sims, so should be GPL. This was decided for “circuit-construction-kit-common” and it got classified as GPL. I didn’t search for a paper trail, but let me know if you need one.

Found the thread: phetsims/tasks#875,

This repo should indeed be GPL. Closing.
