Currently we only handle (fromWayId, viaNodeId, toWayId) turn restrictions and work for handling way-vias is in progress #2681.

What we don't consider at all is no_entry and no_exit which can have multiple from and to ways, respectively - see spec: http://wiki.openstreetmap.org/wiki/Relation:restriction#Members

What we should do is

• detect no_entry and no_exit turn restrictions
• insert multiple (from, via, to) turn restrictions for all from and for all to ways
• add cucumber tests for no_entry and no_exit (might require updating support code)
• update taginfo.json
• update changelog
