/*Script clickSlides.js, completed 7-10-2005. Copyright 2005 by James T. Hawes. All rights reserved. 
Allows user to click through several slides. Also advances commentary in text area. After last slide
(or before first slide), further advance clicks cause the show to wrap around. From the final slide, 
the show proceeds to a rerun of the first slide. From the first slide, the show proceeds to a rerun 
of the final slide. Definitions for the commentary, slide array and length of array appear in the
HTML code body, not here. This method of split coding allow the developer to reuse clickSlides.js. */
