Attached is a draft of a script to form 2d Euler curve approximations.
There is a readme file in the 7zip, if anyone is interested.
Thought I would try to do a Levenberg Marquardt solver algorithm in javascript, and also try
to piggyback onto the arccontinue factory script, for interactive use...

Is there any LM algorithm in MoI?
Is there any way for a script to access the tangent value of a curve, at a selected point?
