func (Coordinate) DistanceTo

func (c Coordinate) DistanceTo(to Coordinate) float64

Distance function returns the distance (in meters) between two points of

approximation of the Earth) through the Haversin Distance Formula for
great arc distance on a sphere with accuracy for small distances

point coordinates are supplied in degrees and converted into rad. in the func

distance returned is METERS!!!!!! http://en.wikipedia.org/wiki/Haversine_formula
