 * Bazillyo's Spiffy DHTML Popup Calendar v. 1.0 © 2000 S. Ousta
 *   - freeware with this comment
 *   - for download size, you can strip all spaces & comments except the © notices
 *   - Thanks to Chris for the domlay() function
 *   - this requires calendarcode.js, calendar.css, and calendarTest.htm
 *   - works in IE4.x, IE5.x, NS4.75 possibly 4.x, NS6 (with slight cosmetic issues)
 *   - Netscape does display some controls overtop of the layer so layout is important
