`nph` opinionated formatter v0.3

[ggibson]

Isn't developer-specific preference -- such as two vs four space tabbing -- a 
developer-specific problem? I imagine `nph`, much like python's `black` to be 
used like a pre-git-commit automatic step to standardize code. Doesn't much 
matter what it's standardized to. This frees you up to display and edit the 
code however you want, without regard to the preferences of your colleagues, 
while the codebase remains standardized, making other automations easier.
