Nodes and ways from Overpass query is not re-used #82
Description
When using overpass queries that fetches relations/ways as well as full node information, the library does not use the available information when later using calls like nodes() or members() on the ways or relations. It tries to fetch the information from OSM if it is not in the cache.
It would be nice if it would place any node or way information in the cache so that future calls will reuse this information, or pass the Element objects onto the other elements for re-use.
At least as an option to the query() call.
