x.__contains__(y) <==> y in x
Returns True if the value is contained anywhere in the data array. The value may be a cf.Data object.
Examples
>>> d = cf.Data([[0.0, 1, 2], [3, 4, 5]], units='m')
>>> 4 in d
True
>>> cf.Data(3) in d
True
>>> value = d[1, 2]
>>> value.Units *= 2
>>> value.squeeze(0)
>>> value
<CF Data: [2.5] 2 m>
>>> value in d
True
>>> numpy.array([[[2]]]) in d
True
