+// Public methods to compute Voronoi diagram of a set of points and segments.
+// Coordinates of the points and of the endpoints of the segments should belong
+// to the 32-bit signed integer range [-2^31, 2^31-1]. To use wider input
+// coordinate range voronoi_builder configuration via coordinate type traits
+// is required.
+// Complexity - O(N*logN), memory usage - O(N), N - number of input objects.
