To programatically interact with a Faasm cluster, or to use more advanced (or
custom) features than those included in the command line tasks (faasmctl -l),
we recommend using the faasmctl API.
After installing faasmctl as a python dependency, you may import any of the
functions defined in faasmctl.util. For an example on how
to use the API, you may see how we upload and invoke functions in the
CPP repo.
