The dodecahedron command creates a regular dodecahedron.
dodecahedron takes three arguments: A,B,C, three points.
dodecahedron(A,B,C) returns and draws the
dodecahedron centered at A with a vertex at B and with an axis
of symmetry in the plane ABC. (Note that each face is a pentagon,
but will be drawn with one of its diagonals and so will show up as a
trapezoid and a triangle.)
