/*
Assumptions:
Files listed in the bar do not link to anything outside the root of the directory
ie. a valid link is "meetings.html" <-- links to file in same directory
ie. an invalid link is "../hi.html" <-- links to file in parent directory
ie. an invlaid link is "candy/thebest/mandm.html" <-- links to file in subdirectory

FIles listed in the link cannot have extra paramters attached and must end in .html
ie. valid link is "iamgood.html" <-- no parameters ends in .html
ie. invalid link is "iambad.php" <-- does not end in .html
ie. invalid link is "iamverybad.php?works=fails" <-- has extra parameters and does not end in .html
ie. invalid link is "iamveryverybad.php?dir=home/iwill/fail.html" <-- dear god, i do not know what will happen

This function works by first taking the link given of the hover and finding the directory leadding up to it
Then the function load the element of class scroller from the remote page into the local page
Then the links loaded into the page are edited to point to the right directory
the whole count system is to control how many times a link is edited.. essentially an IE Hack
