Hierarchical Visitor
The (hierarchical) visitor allows us to visit each element in a booking form.
Elements with children (EO_Booking_Form_Element_Parent) are passed to visit_enter(), to
process that element. Returning true in that method will continue the iteration to its child
elements. Other elements are passed to visit() for processing. An EO_Booking_Form_Element_Parent
is passed to visit_leave() when its children have been processed (or skipped).
A 'process' here is very generic and is defined by the concrete child classes.
