Create CLI with batch support

[jvivian]

Could be split into some optional subcommands areas

Data Preparation

• Help users turn their data into the input used by the pipeline (which we'll change to AnnData shortly, I should have time soon)

Prepare batch inputs

• Allow user to create some sort of runs.json which contains all the information necessary to run the model with different parameters
• Just realized this could be a page very similar to the model runner, but it iteratively "collects" parameters the user inputs until they're done then spits out a json file or whatever with the batch run information

Run Model

• Runs the model given the input data. The assumption is the input data only contains the variables/parameters the user wants to run. Modifying subsets of parameters can be handled by the batch runner.

All of this fixed by #74 !

Misread this as running CLI with batch parameter -- this is about handling parameterized batch runs.
