      Attached 2 new classes:

      1) CoordConstrainedBooleanQuery
      A boolean query that only matches if a specified number of the contained clauses
      match. An example use might be a query that returns a list of books where ANY 2
      people from a list of people were co-authors, eg:
      "Lucene In Action" would match ("Erik Hatcher" "Otis Gospodnetić" "Mark Harwood"
      "Doug Cutting") with a minRequiredOverlap of 2 because Otis and Erik wrote that.
      The book "Java Development with Ant" would not match because only 1 element in
      the list (Erik) was selected.

      2) CustomQueryParserExample
      A customised QueryParser that allows definition of
      CoordConstrainedBooleanQueries. The solution (mis)uses fieldnames to pass
      parameters to the custom query.
