[Building Sakai] LikeService

[csev]

I agree with Aaron's "nice" assessment.  Simple things are elegant.  And it serves as nice sample code for building EB-style services.

A bit of sample code showing how to use the service  in Java might be nice.  Trivial unit tests might be nice too and would suffice for the "Java sample code".

As adoption and use grows, a bit of gentle caching might be needed on the read side.   But there is a place for that and if/when it is needed it should be a simple addition.

Perhaps I am misunderstanding Aaron's suggestion as to where to home this - I don't think it belongs inside the EB code base - it would be nice to keep it separate (as it currently is) and properly connected to EB like any other service.  If EB were in kernel, this probably belongs in kernel too.

Some functionality questions:

- It seems I can like myself :)
- It seems like I can +1 myself or anyone else as many times as I like
- It would be simple to add a "dislike" column as well 

Perhaps I am not web 2.0 enough and don't realize that these features are an expected fact of life for "Like" buttons.
