class MultipleConnectedInteractive from AIS inherits InteractiveObject from AIS
---Purpose: Defines an Interactive Object by gathering together
-- several object presentations. This is done through a
-- list of interactive objects. These can also be
-- Connected objects. That way memory-costly
-- calculations of presentation are avoided.

---Purpose: Initializes the Interactive Object with multiple
-- presentation connections. If aTypeOfPresentation3d
-- does not have the affectation PrsMgr_TOP_AllView,
-- it is projector dependent.

---Purpose: Returns true if the object is connected to others.

-- Returns the connection references of the previous

---Purpose: Removes the connection anotherIObj to an entity.
