speed test on-device code

[ebgoldstein]

as mentioned at the end of #90, we should get the speed of each of the components of the code on the device. the simple way is with well placed time.time() commands.. i.e., https://stackoverflow.com/questions/5849800/what-is-the-python-equivalent-of-matlabs-tic-and-toc-functions#5849861

it would also be cool to do some profiling of the code, but that might require some other tooling..

This is good to know
