Hi Jason, I was wondering how scikit-fmm is proceeding. Does it have extension velocities yet? I noticed that you had added an extension velocities example in the git repository, but nothing has been released yet. Do you think it is at a stage that I can can use FMM and extension velocities from within FiPy? I just recently finished a wrapper for LSMLIB and I want to include scikit-fmm as an alternative choice. I hope to compare them for efficiency using the FiPy examples and see what needs to be updated/fixed in both packages.
