> Issue Type: Bug
> Affects Versions: 4.0, 3.5, 3.6
> Reporter: Matt Juntunen

> When created from boundaries consisting of two intersecting infinite lines, PolygonsSet.getVertices() throws an IndexOutOfBoundsException.
> {{Ex:}}
> {{Line line1 = new Line(new Cartesian2D(0, 0), new Cartesian2D(1, 1), 1e-10);}}
> {{Line line2 = new Line(new Cartesian2D(1, -1), new Cartesian2D(0, 0), 1e-10);}}
> {{List<SubHyperplane<Euclidean2D>> boundaries = new ArrayList<>();}}
> {{boundaries.add(line1.wholeHyperplane());}}
> {{boundaries.add(line2.wholeHyperplane());}}
> {{PolygonsSet poly = new PolygonsSet(boundaries, 1e-10);}}
> {{poly.getVertices(); // throws exception}}
