crazy bug ..code fails on server, passes on laptop

rewrote invocation of shape_postgis stuff to first
define the function, and then call it inside a callback.

so instead of
   shapes_postgis(options)
being the handler, instead

   var s = shapes_postgis(options)

then handle with
   function(req,res,next){ return s(req,res.next) }
get rid of more console.log messages
