Adding Thorax code for individual provider page

- Created basic provider model, view and corresponding handlebars
  template that displays basic provider information without styling
- Edited provider controllers to use Api instead of API
- Added provider route to the thorax router

*Note* The database does not contain any providers with complete
information. All included fields are null. I had to edit a file on my
local copy of the database to see these changes take affect in the UI.
