RelationTraverser should allow to filter which nodes to return

Reported by Andreas Ronge | January 12th, 2009 @ 12:28 PM | in 0.2.0

The following example should only return all locations (e.g. state,city, suburb, street ...) in califonia which has a population of at least 300000:

califonia.relations.outgoing(:sub_locations).depth(:all).filter{|pos| pos.current_node.population > 300000}.each {|location| puts location.name }
