Calibration of multiple models using SCE-UA

[ssheeder]

I'm wondering if anyone has examples of using Spotpy to calibrate multiple models to the same forcing data? I would like to avoid creation of separate spotpy setup classes for each of the different models, but can't figure out how/where to instantiate the variables to calibrate, as the number of variables is model dependent and the provided examples stipulate that calibration variables are to be defined at the class level. Any help is greatly appreciated!
