Looks good. Merging it into ```develop```
merging with upstream
Devise - created model spec for users and view specs for sign in and sign up. Modified application_helper with resource for devise and updated factory for users.
UI restyling of sign up form
restyled session/new & registration/new forms. Added a flash helper to devise_helper.rb (potential smell?). Refactored step definitions to target ID's rather than labels in forms
