A sphere sweep is a single object - not a process - that is the surface
represented by the boundary of all of the space occupied by a sphere if 
it is swept along a curve.  This implementation also allows you to vary 
the radius of the sphere as a function of time.  The result is that you 
can create tubes and other such things that follow spline curves without 
the limitations of tools like my torusspline macro.  By varying the 
radius, you could even make something that looks a bit like a baseball bat 
with just a single object (though if you're not using a lathe for making a
baseball bat, you should be hit with one...)
