Clip Outliers

This new feature would allow a user to clip soundings that are more than a specified vertical distance away from the mean height in a grid cell of a specified size.

This capability is available currently in the 3D Editor, it would be ported to be part of the Filter Toolbars such that it could be iteratively run with differing cell sizes and offset distance.

Note that similar filters of this nature in other software packages sometimes add virtual points to avoid overly clipping steep slopes or boulders. This technique may be considered when implementing in QPS software.
