numpy.NewAxis broken

[doutriaux1]

the follwoing used to work

f=cdms2.open("/usr/local/uvcdat/2.4.1/share/uvcdat/sample_data/clt.nc")
>>> s=f("clt",slice(0,1))
>>> s.shape

>>> zm.shape
(46,)
>>> s2 = s -zm

for now a wrork around:

>>> s,zm  = genutil.grower(s,zm)
>>> s.shape
(46, 72)
>>> zm.shape
(46, 72)

@lee1043 thanks for reporting this bug

maybe 3.0 target?
