[Matplotlib-users] Cmap creation

I'm running into walls trying to create a custom cmap.

Running the example custom_cmap.py unchanged, I get :

AttributeError: 'module' object has no attribute 'register_cmap'
      args = ("'module' object has no attribute 'register_cmap'",)

I've included custom_cmap.py below.  It's a major shortcoming that
there is not a suitable anomaly cmap (with white about the middle).
Please consider this for an addition.

Anyway, what am I missing with this error?  Thanks so much!
