/** 

Breadcrumb javascript from http://www.mickweb.com/javascript/tutorials/breadcrumbs/explanation.html
Edited by Tom Pollard on November 9th, 2005 to include style and image specs, and to remove the root breadcrumb to flightline.highline.edu


Future development needs:
     Convert to title case - done 11-14-2005
     Convert web names to meaningful text - done 11-14-2005
     ie: 
     	libauto to System Administration
     	media to Media Services
     	tpollard to Tom Pollard
     	etc.

Note:  the main html file in each folder must be that same as what is speced in the default_page variable.
