manages a list of BaseRenderer.
A focuspointer can be set and read. GoToNext can be used to switch through the list. if the switch m_Loop is set to true, GetNext loops through the list; after the last it goes to the first. if it is not set, it returnes NULL if it steps behind the last Widget.

Element, that can be focused and held here.
has to be an itk-Objekct in order to use itk-Smartpointer!
