Function intersectionOfSegments

intersectionOfSegments(
a: [VectorPoint<Properties>, VectorPoint<Properties>],
b: [VectorPoint<Properties>, VectorPoint<Properties>],
): undefined | VectorPoint<Properties>
Find the intersection of two segments

NOTE: Segments that are only touching eachothers endpoints are considered intersections
Parameters
- a: [VectorPoint<Properties>, VectorPoint<Properties>]
  the first segment
- b: [VectorPoint<Properties>, VectorPoint<Properties>]
  the second segment
Returns undefined | VectorPoint<Properties>
A point if the segments intersect where the intersection occurs, otherwise undefined
