/*
This javascript is an object oriented version of MI's Story Tools.  Much of the
code here was developed by Lucas Myers.  It has since been slightly modified to
fit into the Reference Site, and some additions have been made.  Gabe Doliner
made it object oriented.

This script is called from and used by the story detail template only
