Changes (by Olly Betts):

 * version:  SVN trunk => git master
 * milestone:   => 1.5.0

Comment:

 In git master `RangeProcessor` has replaced `ValueRangeProcessor` and
 returns a `Query` object, so that one is gone now.

 typeof(uint), typeof(SWIGTYPE_p_std__string) };

 So the current uses are:

 * `Compactor::resolve_duplicate_metadata()`'s `tags` parameter - this is a
 fairly obscure feature, but ideally `num_tags` and `tags` should map to
 some sort of ordered container of strings in the bindings.
 * The `grouping` parameter to `QueryParser::add_boolean_prefix()` and
 `QueryParser::add_rangeprocessor()` - this is essentially a nullable
 string parameter, so that's how it should be wrapped for the bindings.
