=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.
