Do Not Pass Config Dict to Business Logic

[wasciutto]

Currently, the controller methods read the configuration file and pass this configuration dictionary to the business functions.

This creates a sprawl of difficult to maintain dictionary key references in sub-methods that can be avoided by just passing in these configuration options as individual arguments.

I originally did not want to deal with a large number of arguments from configuration, but I think unpacking the config dict is ultimately the better call after dealing with the codebase for a while.

This will entail a decent-sized refactor where I would want some overall-pipeline level tests available first.
