 *  ASCEND Type Retriever 1.2
 *
 *  Purpose:
 *      To extract a type definition from an input file.
 *  Usage:
 *      See the header file for use from within ASCEND.
 *      For stand-alone use:
 *          typer [flags] ascend_type_name input_file output_file
 *              flags: -c  show comments
 *                         If no -c given, strip out comments.
 *  Features:
 *      --Does not descend into REQUIREd files. Only examines input_file
 *        for definitions of ascend_type_name.
 *      --This version DOES handle the UNIVERSAL quantifier.
