{
%Docstring
Implementation of GeometrySimplifier using the Douglas-Peucker algorithm

Simplifies a geometry, ensuring that the result is a valid geometry having the same dimension and number of components as the input.
The simplification uses a maximum distance difference algorithm similar to the one used in the Douglas-Peucker algorithm.
