The macros take a hull that has already been designed, and refines it
by replacing each face with a set of smaller faces.  The edges are
divided and the orginal points are moved slightly as well.  When this
is repeated a few times, the result is a curved surface.  With the
right hull, you can make almost anything.

For a tree macro, the macros should be fed a rough hull of the tree
(which is fairly easy to build); the marso would then make a smooth
tree.
