Update Cloudy test and Cloudy notebook

[bielim]

Update Cloudy test to use lognormal priors.
Update Cloudy notebook such that it can be run with the current version of the CES code. @charleskawczynski: I know that you hate that notebook (or notebooks in general), but until we decide to delete it I'll keep updating it from time to time :-)

I'm fine with keeping the notebook around if you find that it has value. It may be more efficient to use Literate to generate notebooks from the existing Julia script though, so that you don't need to maintain duplicate versions.

I will look into that, thanks!
