Same results as last time:

I confirmed that this run was executing the right install. This branch was installed to /usr/local/lib/python3.8/site-packages/canmatrix-0caf5fe.post12_g81eac11-py3.8.egg and the development branch to /usr/local/lib/python3.8/site-packages/canmatrix-0caf5fe.post11.dev0_gc6a24f3-py3.8.egg
