       * Code example from Zach Leatherman's blog, based on the YUI namespacer
       * Returns the namespace specified and creates it if it doesn't exist

       * YAHOO.namespace("property.package");
       * YAHOO.namespace("YAHOO.property.package");

       * Either of the above would create YAHOO.property, then
       * YAHOO.property.package

       * Be careful when naming packages. Reserved words may work in some browsers
       * and not others. For instance, the following will fail in Safari:
       * <pre>
       * YAHOO.namespace("really.long.nested.namespace");
       * </pre>
       * This fails because "long" is a future reserved word in ECMAScript
       *

       * @static
       * @param  {String*} arguments 1-n namespaces to create
