Isolated Points Filter
- Author: V. Wichmann (c) 2023

Description
The tool allows one to detect isolated points within a point cloud. These points can be either tagged as "isolated" or be removed entirely from the dataset.
A point is assumed to be isolated as soon as the number of points in the search radius is below the specified threshold.
If isolated points become tagged, a new attribute field "ISOLATED" is added that provides the number of neighbours found for isolated points (including the point itself) or zero for all other points.
