Add Focuses, Procedures, Projects, and Tickets to backend

Add models and tables with relationships.
Created models in rails console for testing purposes.
Added routes for each new model (resources :focus)
Added controller for each new model
Added view folder and rabl files for each new model
Rabl files for focus return each focuses projects(with tickets) and procedures
Rabl files for projects return each project with tickets
Tested JSON sent to browser
Rationale for sending everything down with focuses = This way when user logs into the app, they get everything at once and don't have to get anything again.
