f8fc8cb544 Adds sweep and new version of path_sweep to skin.scad, which probably 
needs a name change.  Adds apply(), apply_list() and
affine_frame_map() to affine.scad.  Adds derivative calcluation to
math.scad.  Adds path_tangent, path_normal, path_curvature and
path_torsion functions.  Adds path_length_fraction().
Fixed bug in reindex_polygon where it randomly reverses a 3d path (due
to clockwise check that is bogus in 3d) and put a check in
polygon_is_clockwise to trap this case.

29b682be96 Added lcm() and gcd() and is_integer() to math.scad. Added a couple 
3d examples for supershape() that I snagged from
list-comprehension-demo.  Added repeat_entries to array.scad.  Note
dependence on _sum_preserving_round which is in paths.scad.  Also note
it's possible _force_list (added to math.scad) should be exposed, or
placed elsewhere.
