Add @distance for geo

[davedbase]

It would be really great if there was a function to call and return distance between points or polygons. ie. @distance(PointA, PointB). If it were to return the result in meters that could be really, really handy!

Agreed, this would be awesome to facilitate sorting geo queries by distance to a particular point.

Just came across the need for this feature, in tandem with the near query, that would be cool.
