I need to check the orientation of a polygon for a patch I'm currently 
working on so I thought I would post the code for this here in case 
somebody needs to check the orientation of a roundabout.

  think it only makes sense to check the orientation for a MapShape so 
you'll need to create a temporary MapShape from the MapRoad and check 
the orientation from that object.

Cheers, Ben
