Kudos for a very well done README (and it's not just cribbed from the original project, it explains the new stuff very well and tells what the project is, and gives credit back). So many projects neglect the README.
One question - is it OK to put an MIT license on something that is based on LGPL code? I don't know enough about how the LGPL works (I do know it is less "infective" than plain GPL).
Well two questions: python2, or python3?
