 ************************************************
 * Suppose that data is the form of string that *
 * is passed to a program by an HTTP server via *
 * the Common Gateway Interface.  It has the	*
 * form						*
 *    name=val&name=val&...			*
 * telling what was typed into boxes in a form. *
 * For example, if the form has two boxes 	*
 * called FLAVOR and COLOR, and somebody 	*
 * typed mango into the FLAVOR box and orange	*
 * into the COLOR box, then data the string	*
 * will be  					*
 *     FLAVOR=mango&COLOR=orange		*
 *						*
 * getBinding(name, data) returns the string	*
 * that was typed into the box called name.     *
 * For example,					*
 *   getBinding("COLOR", 			*
 *		"FLAVOR=mango&COLOR=orange");	*
 * returns "orange".				*
 *						*
 * The returned string is stored in memory that *
 * is allocated using 'new'.			*
