OUT = LINESEGMENTINTERSECT(XY1,XY2) generates intersection analysis between the line segment sets given in XY1 and XY2. Code can handle coincident and parallel lines.

The main emphasis is on speed. The code is fully vectorized and it runs pretty fast (orders of magnitude) compared to some of the previous postings.
