Defines functions:
1. binomial()
2. convolve()
3. all_numeric()
4. is_addable()

Input data check in all functions.

Recoding of:
1. cumsum (a non-recursive version)
2. median()
3. count_true() (more efficient version)
4. polynomial functions so that a zero polynomial is represented by [0] and not by []

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.
