Summary:

Note: this PR should not be merged. This is to have this PR run through continuous integration.

This is the code for a prototype for simplified command line structure.

Intended Effect:

This should pass all tests.

How to Verify:

Run any command that you would from CmdStan. There’s a bit of translation that needs to be done, but this should reproduce CmdStan’s results identically.

Side Effects:

Documentation:

This is lacking a lot of doc. If it’s to make it out of prototype, it’ll need more documentation.
