Added polynomial root finding and complex math to math.scad. Changed
...
path_to_bezier to new algorithm (which uses polynomial roots). And
updated path_smooth to use the new code.
Also removed extra (?) include<skin.scad> and
include<strings.scad> from rounding.scad and
removed the common $fn=36 that was forced on all the examples. (May
break something...we'll look at the examples and see.) I added $fn=36
to some examples.

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.

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.
