Computes a Geometry representing all the points in this Geometry and other. @param other the Geometry with which to compute the union @return a set combining the points of this Geometry andthe points of other @throws TopologyException if a robustness error occurs @throws IllegalArgumentException if either input is a non-empty GeometryCollection
