[Javamatch-developers] Replace MatchList, OrList, AndList with QuerySet

[<wal...@ph...>]

Hi all,

I'm replacing MatchList, AndList and OrList with a single new query: 
QuerySet today.

Advantage of QuerySet: it can deal with both "required" and "preferred" 
sub-queries.

The OrList functionality (Take the (weighted) average of all subqueries) 
has been moved to QuerySet.addPreferred()

The AndList did not provide really useful results so far. Its intention: 
Add a subquery that _must_ be 100% fulfilled, or it won't be included in 
the result set. This is now done by method QuerySet.addRequired().

If there is any reason to keep / revert the old classes, please let me 
know.

Regards,
Walter

That's why pre-1.0 releases are my favourite, change the code, don't 
bother about legacy ;-)
