Fuse n' Weld MaxScript updated

Been working on some vector artwork which needs some cleaning up so I've updated my old MaxScript called 'Fuse n' Weld' which I wrote way back for Max version 3 but didn't work with current versions.
Still a useful script so hosting it at Google Code for CNC Toolkit.

Takes all vertices in a shape, compares them to their closest neighbor and moves them to an average position if within the threshold. "Fuse" moves only, "Weld" moves and welds.
If many vertices are within the threshold, it only operates on the closest so it may be necessary to run the script a couple of times. If multiple shapes are selected then all shapes are combined.
Detach All Splines; dissolves a shape or shapes into it's component splines.

My other old MaxScripts are on my website at; http://www.cnc-toolkit.com/maxscript.html
