Public function which is used to create a television episode's short description

Parameters:
	-- |episode_num=		— optional; The episode's number.
	-- |season_num=			— optional; The season's number.
	-- |season_num_uk=		— optional; The season's number if using the British "series" term.
	-- |series_name=		— optional; The TV series name.
	-- |multi_episodes=		— optional; Setting "yes" will default to a two-part episode.
								If there are more than 2 parts, set the value to the number of parts.
	-- |not_dab=			— optional; Set if the TV series name has parentheses as part of its name.
	-- |special=			— optional; Setting to "yes" will set the description as a "special episode".
								Any other value will replace the word "special" with the one entered. For example "special=recap" will create "recap episode".
	-- |single_season=		— optional; Set if the series is a single season series, such as miniseries or limited series and does not need "1st season" as part of the description.
