Title: Default to WMAP9

This minor change in `cosmology` just changes the default cosmology to be WMAP9.

I can see no reason not to make this change, as WMAP9 should be the last WMAP results (the satellite is no longer collecting data). Perhaps in the next version we'll have Planck results.

@nhmc @aconley does this sound fine to you?
