#fitnesse_to_features(wiki_page) ⇒ Array

Return an array of Cucumber tables found in the given FitNesse content file, or an empty array if no tables are found. Each table in the array is in the same format as a table passed to the do_table method; that is, a table is an array of rows, where each row is an array of strings found in each cell of the table.
