I've done an initial pass adding costs to functions which take a single 
polygon, or a single polygon and other non-geometry arguments. You can 
see the diff in the form of a PR at 
https://github.com/postgis/postgis/pull/104. Some comments would be 
appreciated before I look at non-polygon functions and functions which 
take multiple geometries.
