Admin can view a list of all reviews and delete them--all tests passing....

Added a page for admins where they can view a list of reviews to delete if necessary
Fixed a typo in user deletes own review spec
Instead of dealing with two cases inside of your `authorize_admin` method (the case where `current_user` is and admin vs. isn't an admin), I'd us the `authenticate_user!` helper method from Devise to handle the second case.

```ruby
module Admin
  class ReviewsController < ApplicationController
    before_action :authenticate_user!
    before_action :authorize_admin

    #...

        private

    def authorize_admin
      if current_user && current_user.role != 'admin'
        flash[:notice] = 'You are not authorized to do that.'
        redirect_to '/'
      end
    end
  end
end
```
