Missing Daisyworld demo

[CommonClimate]

The model catalog mentions a Daisyworld model but there is no corresponding demo.

@CommonClimate this is related to issue 44. We should either add a demo, or pull it for the time being. I'm tempted to say let's hold it back for now. We have a lot going on tuning up the existing zoo and this one probably needs some additional thinking to support appropriately.

Yes, I agree. We can revisit that when you put together the GEOL351 labs as a paper.
