modelFitEMCEE error: local variable 'modelset' referenced before assignment

Hi Adam,

I hit a problem when running the modelFitEMCEE routine. See the attached extract from a Jupyter notebook for details. Hope this is an easy fix!
Cheers,
Dave.

Hi Adam,

It looks like I didnt attach the error text to my original message. Here it is:-
