#
# · Groups stations by continents and countries. Where Europe seems to be the
# main category (empty "" path), while U.S. is labeled "/world", and Canada
# and Asia etc. again a subpath "/world/canada" even. The .catmap{} assigns
# paths to titles.
#
# · Playlist formats vary wildly. Therefore this module comes with a guessing
# method (super crude) of its own.
#
# · The audio-format-from-URL guessing should be generalized out of here perhaps.
#
# · Each station is in a <tr>…</tr> block. Invidual regexps are used for field
# extraction afterwards (instead of a block match).
#
# · Entries may contain more than one streaming url. Each accompanied by a
# bitrate. → Therefore the .best_url() sorting method.
#
# · Later versions might of course use multi-urls again…
