New description:

 Given a PostGIS long/lat WGS 84/NAD 80 geometry point (and an optional
 option of returning the street range (for cross streets) - boolean that
 defaults to false), return an array of approximate street addresses and
 other related items (reverse interpolating along the edges and street
 address ranges).

 Other related items would be an array of cross streets (this will include
 street range if include_street_range is tru), array of centerline points
 (if the  point is say at the corner of 2 streets) would return the
 interpolated centerline points) or just one.

 This will be useful for example managing fleets of cars or emergency
 response when you get back a long lat from GPS devices, but don't know
 where that is along your road networks or if its parked off the street or
 possibly  at a site)
