snaptogrid()  is a better descriptive function. 

for these helper functions
 Need to document
     1 -  this is a PostGIS extension to SFSQL  (so users understand 
standards vs app specific)
     2  - this function may return a heterogeneous collection of  stuff 
and may need to be filtered
                for the desried types.
     3 -  this function does not enforce the assertions on geometries it 
creates and the results
                may need to be cleaned.
