Cuts holes in polygonal features by making polygons completely enclosed in other polygons into holes of the containing polygon.

The DonutBuilder assumes that the input area features are topologically clean. Further, it is assumed that any two input polygons within a group either have a strict containment relationship, or are not overlapping.

Aggregate features are decomposed recursively to their components and non-area features will be output via the <Rejected> port.
