compoundAll feature request

[craftoid]

We had a little workshop, where we used the compound function quite a lot :) The participants asked for a function similar to combine that would allow them to create a compound of several shapes at once.

I think a compoundAll function that takes a list of shapes to create a compound would be quite useful. Here's a demo of how it might work ...
