/**
 * jquery 'plugin' for creating a tagcloud
 * This plugin requires swfobject.js to be included (tested on swfobject 1.5)
 *
 * usage:
 * create a div containing a-elements representing the tags, for example:
 *
 *       <div class="tagcloud">
 *         <a href='behandelingen/depressie/index.html'>Depressie</a>
 *         <a href='behandelingen/paniek/index.html'>Paniek</a>
 *         <a href='behandelingen/rouw/index.html'>Rouwverwerking</a>
 *         <a href='behandelingen/schokkende-ervaring/index.html'>Traumaverwerking</a>
 *         <a href='behandelingen/seksueel-geweld/index.html'>Seksueel trauma</a>
 *         <a href='behandelingen/icheck/index.html'>iCheck</a>
 *         <a href='behandelingen/aanpak/index.html'>Online!</a>
 *       </div>
 *
 * then, in your onload handler, call:
 *
 * $('.tagcloud').tagcloud();
 *
