Add signaling colors in table 'model parameters'

[cjhollebrandse]

The table 'model parameters' shows the parameters that gives the best fit. It happens that certain parameters deviate considerably from what is physically realistic.
For less advanced users, the interpretation of the model results becomes easier if unrealistic results are given a signaling color (yellow, orange, red). In case of a color code it's advisable to generate a new model or to be careful with conclusions.

I think this is fairly easy to implement.

Thanks @cjhollebrandse for your suggestion! I like the idea of color coding the parameters table.

However, I don´t think we can really determine whether parameters are physically realistic. There's probably no way to include code that would work well in all situations.

Having said that I do think we can use color codes to signal if parameters hit the parameter bounds, for example. And maybe also think of a way of signalling when response times (e.g. t_99) is longer than the oseries. So basically incorporating the warning section in the fit report in the results plots.
