Returns a recursively "normalized" form of this query. The
        normalized form removes redundancy and empty queries. This is called
        automatically on query trees created by the query parser, but you may
        want to call it yourself if you're writing your own parser or building
        your own queries.

        >>> q = And([And([Term("f", u"a"),
        ...               Term("f", u"b")]),
        ...               Term("f", u"c"), Or([])])
        >>> q.normalize()
        And([Term("f", u"a"), Term("f", u"b"), Term("f", u"c")])

        Note that this returns a *new, normalized* query. It *does not* modify
        the original query "in place".
