* @short Renders a view from a controller other than self.
* @details This method renders a view from a controller other than self,
* for example when embedding a view into another view.
*
* The <tt>params</tt> array has the same semantics of the <tt>render</tt> method,
* with the following additions:
*
* <tt>controller</tt>: the name of the controller responsible for the view (defaults to self).
* @param params Parameters defining how the rendering should be realized.
