[LDCad] Simple LDCad script

[N. W. Perry]

Yes, just write them without the value assignment.

I couldn't get them to work except inside the loops themselves (which meant I had to declare them in both loops). But the cnt variable does, for some reason.

scripts can't actually modify lines on a string level (mostly because of the undo tracking), but you get the same effect by creating a new line and deleting the old one.

For an example of this see the global mlcad.lua script.

Yes, I'll be studying that one tonight. :-)
