The interpolation method comparison notebook does take too long to run on binder

[cchwala]

Probably due to limited RAM on the binder pods, the last cell of the example notebook that compares IDW and Kriging does not complete when run on mybinder. Not sure how to solve that. Using a smaller number of CMLs will probably help, or changing the Kriging application to its rolling-window version because, if I recall correctly, this uses less RAM.

Update: Apparently the notebook runs, but the last cell takes way longer (5 minutes or more) than on my laptop. Hence, the user will probably think it stalled. I keep this issue open, because each cell in the example notebooks should ideally run within some seconds or at least indicated with a progress bar that it is doing something.
