How to intersect a (large) surface model with (many) lines?

There are two similar functions geomtools.intersectionPointsLWT and trisurface.intersectionWithLines.

Recently, the trisurface.intersectionWithLines has been improved by adding some features:

-work with lines, but also segments and rays (half lines)
-detect intersections also on triangles'edges and vertices
-be fast with large models (and with low memory usage)
-return all info: a fused list of intersection points and the indices of point, line, triangle per intersection occurrence.

It would be nice to have one final version (either in trisurface or geomtools), so suggestions/comments/contributions are welcome!
