What is the "Private" module for?

• https://github.com/pragdave/mix_generator/blob/master/lib/mix/tasks/gen.ex#L5
• https://github.com/pragdave/mix_generator/blob/master/lib/mix/tasks/gen.ex#L27

I'm sure it's just a closed-source helper, but what does this module actually provide? Is it required that users of mix_generator have access to the module? Should potential contributors know what it's doing? In either case, I'd appreciate some documentation about it somewhere in the readme potentially.

I ask only out of curiosity; if you'd rather it stay secret, that's totally fine. 😄
