* For a case with only static geometry, make sure it is possible to create a contour map
* Make sure the grid model is open before accessing data
* Make sure the picked polygon points are located above the grid model
Improvements:
* Well Target Candidates: Add filtering by binary result
* Well Target Candidates: make result grid cell count configurable.
* Well Target Candidates: Improve ui ordering.
* Well Target Candidates: compute probability, and simplify vector names.
* Optimization: Avoid expensive unintended duplication of data
