genutil.averager throws a weird exception when using a tuple for 'weights'

[jypeter]

It took me some time find out that you have to use a list and not a tuple for the weights parameter. Can you update the code so that a tuple is accepted, or a better error message is printed?

An example below of what I got, with a slice of your clt.nc test file

>>> cdutil.averager(clt, axis='xy', weights=['weighted','weighted'])
variable_140
masked_array(data=62.71149853,
             mask=False,
       fill_value=1e+20)

>>> cdutil.averager(clt, axis='yx', weights=('weighted','weighted'))

@jasonb5 another usability/doc tweak here

Also a good candidate for displaying readable error messages ;-)

We'll fix this to support list or tuple.
