Yaml dependency not auto installing

[nickl-]

@alganet Could you please provide more information about this issue so that we can ensure that it gets addressed.

PyYaml was the last dependency I thought would be giving us uphill as it does seem to be the de facto yaml library for python and argparse is also the way forward it seems and beaker seems popular but was mainly implemented because I was unable to wrap my head around memoize at the tart of this python journey and beaker got the job done easily.

We may want to consider memoize again any thoughts on this? More on this at #16
