[Research] Railtie

[aaronmallen]

I've found the documentation for Railtie surprisingly lack luster. I would rather add railties as an explicit dependency for the gem but have been unable to get the railtie to do the things I want it to do.

A few things I'd like to accomplish:

• Move rails related configuration to Railtie #121 Rails related configuration (i.e. directory, and context generation) as part of the railtie not a separate config class. (see: ActiveInteractor::Rails::Config)
• Add the interactor directory to autoload_paths #120 app.config.autoload_paths in a railtie initializer (to autoload the chosen interactor directory)
• #101 & ActiveRecord helper methods #119 helper method injection for ActionController and ActiveRecord

Problems I'm having:

• part of the problem is the gem name is activeinteractor but we need to require active_interactor, I've gotten around this with the install generator creating an initializer that requires active_interactor however I'm not 100% sure when this gets loaded during boot.

Research and create a POC Railtie class that accomplishes all these things.
