This routing allows the creation of urls like:
- http://www.mysite.com/solutions will route to CategoryController#index with the categories list
- http://www.mysite.com/solutions/widgets will route to ServicesController#index with all the services belonging to the "widgets" category
- http://www.mysite.com/solutions/widgets/awesome_widget will route to ServicesController#show with the page showing the details of the "awesome_widget" service
This implementation will need the use of the friendly_id gem (https://github.com/norman/friendly_id) in order to generate and use the category and service's names as id.
