e06519bbfb changes to hide recursion args and avoid repetitive arg validations 
cumsum broken in two to hide recursion args and avoid repetitive arg validations.

back_substitute changed to avoid repetitive arg validations in the recursion.

minor change in deriv2 and deriv3 to avoid an unecessary call to is_matrix.

change in is_matrix for better performance

any() and all() broken in two to avoid repetitive arg validation in the recursion and to hide recursion args.

change in polymult to call convolve

break of poly_div in two to avoid repetitive arg validations in the recursion.

7aab27266f 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.

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.

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.
