Support for __main__.py about pyflow

[David-OConnor]

As you've discovered, this is due to limitations on Pyflow's CLI. I think it would be nice to support the flow you tried, since it's intuitive, and consistent with existing python syntax. I'll add it.

I can confirm this. There's something wonky with the arg parsing handling. I think I need to re-organize that section of the code; making the initial change should have been easy, but I ran into trouble. May switch off the structopt dependency, which manages this.

Possibly related: It seems that pyflow just tries to consume all flags, even those that were intended for the python script I'm trying to run.

myproject>pyflow run.py --test
error: Found argument '--test' which wasn't expected, or isn't valid in this context

USAGE:
    pyflow [script]... [SUBCOMMAND]
