+that have already been selected. C<get_dids> will then return an arrayref of
+the possible values for the next selection level. Note that these are not
+actual DIDs except at the lowest level.
+
+Generally, 'state' alone will return an array of area codes or region names
+in the state.
+
+'state' and 'areacode' together will return an array of exchanges (NXX
+prefixes), or for some exports, an array of ratecenter names.
+
+'areacode' and 'exchange', or 'state' and 'ratecenter', or 'region' by itself
+will return an array of actual DID numbers.

+Passing 'tollfree' with a true value will override the whole hierarchy and
