The RatingService will allow users to apply ratings to content nodes in the repository.
There will be a number of built-in Rating Schemes and support to add more by the usual extension mechanism.
Out of the box, we envision a 'likes' scheme (user X likes this document) and a 'star' rating
(user X gave this document 3 out of 5 stars).
Content model for ratings.
Spring config includes two out-of-the-box rating schemes
Various basic infrastructure classes for Ratings, RatingSchemes and the service itself.
Basic CRUD for ratings in a Java foundation layer.
Associated JUnit tests.
The next contribution will add support for per-node average and total ratings and associated tests.
