Creates a TIN using a point set simplification algorithm.
This is an interphase class for point set simplification methods. In this class, the main processing required to use point set simplification techniques in square tiles is defined, but the actual point set simplification method is defined in child classes, one for each method.
Thus, this class is responsible of running the common part of these methods, which is basically to detect border and feature edges in the original data, create polylines from those, and simplify them separately. Once the polylines have been simplified, the rest of point sets are simplified (using the method implemented in each child class) and triangulated in the XY plane.

| borderSimplificationMaxDistance | Maximum error for polyline simplification |
| borderSimplificationMaxLengthPercent | Maximum length for an edge in the simplified polyline. This prevents oversimplification in planar tiles. |
| minFeaturePolylineSize | Minimum number of connected edges in a sharp feature polyline to consider it during processing |

Create a TIN from a set of points.
While it does not impose any regularity on the input points, the use of constrain<X>Vertices is restricted to the shape of the convex hull of the input point being an axis-aligned rectangle.
| dataPts | Input 3D point set |
| constrainEasternVertices | Flag indicating whether the vertices on the eastern border of the tile should be preserved or not |
| constrainWesternVertices | Flag indicating whether the vertices on the western border of the tile should be preserved or not |
| constrainNorthernVertices | Flag indicating whether the vertices on the northern border of the tile should be preserved or not |
| constrainSouthernVertices | Flag indicating whether the vertices on the southern border of the tile should be preserved or not |
