 * Either of the above would create DWI.property, then DWI.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>
 * DWI.namespace("really.long.nested.namespace");
 * </pre>
 * This fails because "long" is a future reserved word in ECMAScript
 *
 * @method namespace
 * @static
 * @param  {String*} arguments 1-n namespaces to create
 * @return {Object}  A reference to the last namespace object created
