#3197: SQL function for GEOSEqualsExact

 This enhancement request is to add an SQL function to access
 GEOSEqualsExact from the GEOS C API to find geometries that are equal, up
 to a specified tolerance. A suggested prototype would be:

     boolean ST_EqualsExact(geometry A, geometry B, integer tolerance
 DEFAULT 6);

 Although a name ST_AlmostEquals might better describe the desired
 operation, since it is designed to provide equality for inexact
 geometries.

 External to GEOS, it is used in Shapely as
 [http://toblerity.org/shapely/manual.html#object.almost_equals
 object.almost_equals](other[, decimal=6])
