/* \brief Extract a dot-bracket structure string from (multiline)character array
 *
 * This function extracts a dot-bracket structure string from the 'rest' array as
 * returned by read_record() and returns it. All occurences of comments within the
 * 'lines' array will be skipped as long as they do not break the structure string.
 * If no structure could be read, this function returns NULL.
 *
 * \see read_record()
 *
 * \param lines   The (multiline) character array to be parsed
 * \param length  The assumed length of the dot-bracket string (passing a value < 1 results in no length limit)
 * \param option  Some options which may be passed to alter the behavior of the function, use 0 for no options
 * \return        The dot-bracket string read from lines or NULL
