Added a ``label`` parameter to the :class:`.Barrier` class's constructor
|
|
and the :meth:`~.QuantumCircuit.barrier` method which allows a user to
|
|
assign a label to an instance of the :class:`~.Barrier` directive. For
|
|
visualizations generated with :func:`~.circuit_drawer` or
|
|
:meth:`.QuantumCircuit.draw` this label will be printed at the top of the
|
|
``barrier``.
