A wrapper for the Boost Voronoi library, allowing creation of Voronoi diagrams for points and straight line segments.
The only function in the library is get_edges which takes a vector of Points and
a vector of Segments with integer coordinates.
It returns Vector{Vertex}, Vector{Edge}. The vertices have Float64 coordinates.
Edge.start_index and Edge.end_index are indices into the vertex vector. They can be 0
if the edge is unbounded at that end.
Edge.site1 and Edge.site2 are indices into the array of points, followed by the array of segments.
I.e. if there are 3 points and 5 segments, site1 = 6 means that the first Voronoi region of this
edge belongs to the third segment.
Edge.is_primary specifies whether the edge is a boundary between two primary regions (points or segments).
An edge that is not primary is a boundary between a segment and one of its own endpoints
(See Voronoi basic tutorial).
