I am attaching an ipelet for computing the total length of a set of 
segments. It should at least be helpful for task 1.
For 3 and 4 you should be careful to use the correct API calls

> Dear all,
> I have been using Ipe for some years now and now I wanted to move further and try to make a small ipelet which could be helpful in my daily work.
> I plan/hope to make an ipelet which can change a straight line into a wave like line by:
> 1)      Extract the coordinates to the end-points of the curve
> 2)      Add control points suitable locations between the end-points
> 3)      Draw a Bezier curve using the control points
> 4)      Remove the straight line.
> Since I'm quite new in this I was wondering if somebody could help me in the right direction? Right now I'm struggling just with extracting the coordinates for the end-points so just to get me started on that would be helpful.
> Best regards,
> Jens
