Coordinate from nlsr.log after nlsr reads it.

If you see these angles between Cagliari and Padua, they are different in the conf file, but here NLSR rounded it to four digits which made the angles same. Thus, if the angle and radius are same, the distance calculation fails with the following message.
copelabs/log/nlsr.log:9706:1541300372.280126 WARNING: [nlsr.route.RoutingTableCalculator] Could not calculate hyperbolic distance from /ndn/padua-site/%C1.Router/cs/padua to /ndn/cagliari-site/%C1.Router/cs/cagliari
Same is happening for some additional nodes.

- Subject changed from NLSR rounds the actual hyperbolic angle and radius to 4 decimal place. to NLSR prints the actual hyperbolic angle and radius to 4 decimal place.
- Priority changed from High to Normal
Just need to specify the precision when printing.
We do need to define the difference needed between angles of nodes on same location more precisely. So we will avoid getting a diffTheta of zero.
