feature-by-feature: when handling big features the tool is crashing due to a long waiting time

[dieuska]

in the feature-by-feature 1*5 calculations are done for one feature to determine the predictions.

For big polygons this results in minutes and minutes of handling; resulting in a crash of the tool.

Some options.
*Prevent that these features are processed

• do less calculations for these big areas,f.e only for every meter
