[Visualpython-users] Unum

I tried doing 4.P.89 and 4.P.90 using the Unum package for keeping
track of units.  I found this quite nice, as it caught several typos
where I had the wrong variable causing the wrong units.

It would be even nicer if object.pos,.length,.axis, ... could be
specified with units, rather than having to be converted to pure
numbers.
