### 12.4.6 Find the isobarycenter of a set of points in space: isobarycenter

See section 11.6.10 for isobarycenters of objects in
the plane.

The isobarycenter command takes a list (or sequence) of
points and returns and draws the isobarycenter, which is the barycenter when all
the points are equally weighted.

Input:

IB := isobarycenter(point(1,4,0),point(1,-2,0))

then:

coordinates(IB)

Output:

[1,1,0]
