Moving ToC in DokuWiki

/*
 * JavaScript to move DokuWiki Table of Contents position from the default
 * location to within the first element with class='wrap_movetoc' and
 * recolors it to match the current ToC of Wikipedia.
 *
 * Creation of a div with class='wrap_movetoc' can be accomplished with the
 * plugin "Wrap" and creating an empty <WRAP movetoc {size}px></WRAP>
 * and placing that where you want the ToC to appear.
 *
