/*
# ABOUT THIS SCRIPT
#
# js_paths.js takes the current document's location.href and splits it up into its
# various elements: protocol, folder hierarchy, and file name.
# It then offers choices if and how to display these elements.
#
# There's a built in naming convention that can be overridden at will for specific
# folders and/or files.
#
# Finally it puts everything back together and spits out the breadcrumb.
#
# HANDLING OF FOLDER HIERARCHY
#
# Since js_paths.js was created to work offline
# unwanted results are to be expected, like a breadcrumb that is so long that it fills half the page
# because of a gazillion folders in its path.
