feature #907 sprint5 :
New property in the suggestions: the actual number of comments let by users. This new property is loaded by the SuggestionBoxService by using the CommentService. This property is now rendered with
some suggestions as expected by the templates provided by Aurore.
The most commented suggestions are now displayed in the main page of the Suggestion Box application. They are managed at client side by AngularJS and at server side by a criteria processor,
SuggestionFinderByCriteria, that uses for doing both the CommentService to find the more commented publications of type Suggestion and the SuggestionBoxService to fetch the corresponding
suggestions.
