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.

Changed the input parameters and the output structure. Now the analysis can be done between two sets of line segments. Analysis also provides more information about the intersections.

Please see the CHANGELOG in the comments.
