Setting PYTHONPATH is unnecessary?

[ngoldbaum]

It looks like at least the simple advection problem suggested in the readme runs fine on my Python3.7 setup without first setting the PYTHONPATH environment variable to point at the pyro2 directory. Is it still necessary to set that for some other purposes?

If pyro is run from within the main pyro directory, then setting the PYTHONPATH environment variable is unnecessary. However, if the pyro module is imported from within a different directory (as it in is in the notebooks in multigrid/ and examples/), then I believe it will not work unless the pyro directory has been added to the python path.

This would no longer be the case if we made pyro pip-installable, as you suggest in #75

Ah I see. Maybe you want to add a note to the readme and install instructions that setting PYTHONPATH is only necessary if you want to use pyro as a module, not if you only use the pyro.py script.

Good idea - I've fixed this in 08c7b61
