class IdenticRelation from AIS inherits Relation from AIS
---Purpose: Constructs a constraint by a relation of identity
-- between two or more datums figuring in shape
-- Interactive Objects.

---Purpose:
-- Initializes the relation of identity between the two

-- aPlane is initialized in case a visual reference is
-- needed to show identity.
IsMovable(me) returns Boolean from Standard
---C++: inline
---Purpose:
-- Returns true if the interactive object is movable.
