This class is responsible for providing the core algorithms to detect for a view
all the 3-nodes access paths, combining the searches among all types of rights and structures.
The form is ' Detailled name: KKKK + Source(s): FFFF + Target(s): NNNNNNNN +
Right(s): jjjj| kkkk| mmmm| ', where the detailed name has the form:
'privilegeType || nickName || first right'.
This interface is responsible for listening the events
fired by one main BaseObject (the main source) as ACSRun
and ViewInBase - and also the events fired by the main source objects-
for updating the unique JTree which is associated
to this TreeBaseListener and which displays the main source objects.
This class is responsible for managing viewable trees for an ACS or a view,
and more precisely the TreeBaseListeners associated to these trees,
and for managing the Explorer tree creation.
