Include EmptyQueryResults class for easier DAO implementation

[GoogleCodeExporter]

It would be great to have an implementation of the QueryResults<T> interface 
for empty query results. I implemented a DOA using the BasicDAO class. I have a 
custom find method which can return an empty query result even before i query 
the mongodb itself (It does some work to narrow down the set of eligible 
documents).

In those cases i want to return an empty QueryResult. It's not a big deal to 
implement one but as the creation of custom find methods is encouraged in the 
documentation there should be an easy way to do so.

Can you describe what a empty query result is? Is it just something which 
doesn't query the server?
