// .NAME vtkAlgorithmOutput - Proxy object to connect input/output ports.
// .SECTION Description
// vtkAlgorithmOutput is a proxy object returned by the GetOutputPort
// method of vtkAlgorithm.  It may be passed to the
// SetInputConnection, AddInputConnection, or RemoveInputConnection
// methods of another vtkAlgorithm to establish a connection between
// an output and input port.  The connection is not stored in the
// proxy object: it is simply a convenience for creating or removing
// connections.
