change license to MIT?

[StefanKarpinski]

I was looking for LGPL packages, suspecting that there should not be many since for a Julia package there's no such thing as "linking" making LGPL equivalent to GPL. I found this package, which appears to be LGPL because it's a wrapper around an LGPL library (which is dynamically linked, so that makes sense). Wrapper code need not have the same license as the wrapped library, so this package could and arguably should be MIT licensed. As it stands, whereas CUTEst can be used with/by non-open source software so long as modifications to CUTEst are released in accordance with the LGPL, CUTEst.jl cannot be used with/by non-open source software, which I don't think was the intention. Since there are still relatively few contributors, getting permission for a license change should be tractable.
