remove / invalidate connected camera of 1d/2d plot

[Former user]

If a camera can be assigned to a plot handle h of type plotItem via

h["camera"] = myCamera

it would be nice to stop the camera connection via

h["camera"] = None

[M. Gronle]

fixes issue #98: camera can be disconnected from plot by assigning None to the camera property:

myCam = dataIO("DummyGrabber") [i,h] = liveImage(myCam) h["camera"] = None #disconnect
