revise Scorer visitor API
-------------------------

                 Key: LUCENE-3330
                 URL: https://issues.apache.org/jira/browse/LUCENE-3330
             Project: Lucene - Java
          Issue Type: Improvement
            Reporter: Robert Muir
             Fix For: 4.0


Currently there is an (expert) API in scorer to allow you to take a scorer, and 
visit its children etc (e.g. booleanquery).

I think we should improve this, so its general to all queries.

The current issues are:
* the current api is hardcoded for booleanquery's Occurs, but we should support 
other types of children (e.g. disjunctionmax)
* it can be difficult to use the API, because of the amount of generics and the 
visitor callback API. 
* the current API enforces a DFS traversal when you might prefer BFS instead.
