Added Delayed Job

For some reason, the delayed_job gem wasn’t properly installed when the
project was set up. I’ve corrected the problem and installed
delayed_job.
Installed Localeapp and Slim

I’ve installed the localeapp and slim gems for easier view development.
Added rake task for localeapp

I added a rake task to manually send translations to locale app for
future convenience.
Modified the application config

I modified the application config to shut up a deprecation error and
help the localeapp gem.
Created the businesses controller [Finishes #64093666]

I created the businesses controller to satisfy the cucumber story. The
current controller has one method, :index, which renders a list of
businesses.

The list is currently not paginated or filtered. This will need to be
modified in the future.
