Adding username as a requirement for user sign up.

While implementing a username column to the Users table I got some failing test cases that are default for the template and noticed that the Users::RegistrationsControllerTest already has username in the setup for the user params but it doesn't seem to be used anywhere when I do a search of the codebase.

I want to be sure that I'm not accidentally writing over anything or creating a column that will clash with anything. Does anyone know if username is already being used? Maybe in one of the gems I'm unfamiliar with?

Just follow the Devise wiki for adding Usernames. 👍
