+=item tower_sector_sql HASHREF
+
+Class method which returns a list of WHERE clause fragments to 
+search for services with tower/sector given by HASHREF.  Can 
+contain 'towernum' and 'sectornum' keys, either of which can be 
+an arrayref or a single value.  To use this, the search needs to
+join to tower_sector.
+
+towernum or sectornum can also contain 'none' to allow null values.
