/* Bread crumb script
** Judy Schaefer, Interactive Studios, i-stuff.com, 11/15/2007
** Reads the path from document.location.href and writes it out in the form of 
** breadcrumbs. Use underscores in your file & driectory names to have them 
** replaced by spaces in the breadcrumbs. The first letter of each "word" is 
** automatically capitalized. Set sSeparatorto determine the separator character 
** between crumbs. The current page is not hyperlinked.You can override the name 
** of the current page by passing in sPageName, otherwise it's determined from 
** the file name.
