Residual Plots on snpy Plotting Function

[JamesBetts5]

I have been using SNooPy to plot light curves in 3 bands and have been plotting them on a single plot with each band offset to allow for better viewing. A feature I think would be really nice would be to be able to plot residuals under this main plot to show how well the model curves fit to the data. Perhaps there could also be the option to specify which bands you'd want to plot the residuals for. This would be a really useful feature.
