Added new function to prototype: placeData();

    /**
     * Automatically places properties from this._params object
     * into page.
     *
     * For example, consider the following DOM:
     *      <div data-sejs='Name'></div>
     * Whatever value is provided for the parameter 'Name'
     * within the URL will be automatically placed into
     * the element.
     *
     * @method placeData
     * @param
     */
