decoratePath about diagrams-doc HOT 2 OPEN

I agree we need a better example of decoratePath. In fact, I think the above code is a better way to make that triangle of dots, even with the old semantics of trailVertices! So it was never a very compelling example even to begin with.

I would actually go farther: I think we ought to deprecate decorateTrail and decoratePath, and add a function to lay out diagrams at a list of positions. (We already have position but we should make an unzipped version of it too, often when I use position I find myself using zip as well.) Then the focus turns to creating powerful/useful methods for constructing lists of points. Getting the vertices of a trail or path is only one such method.

That's a very good idea. I also almost always use zip with position. I'll make a branch and code it up, it should be very easy.
