Docs needs a table of contents page

[68267a]

I've found myself digging through the docs folder for the markdown file relevant to the module I'm trying to use, and opening the preview manually. It would be great if dotSCAD had a cheat sheet or table of contents with links to each file, a quick syntax example, and a short description like the OpenSCAD cheat sheet. It could even be updated dynamically in pretty much any language.

Currently it looks like every line has the function name on line 1 and the description on line 3.

Syntax would be a bit more difficult, but I think it's a necessary addition. Examples are great but any man page or powershell help also has syntax laid out.

A super rough example would be something like this:

Module	Description	Syntax
arc	Creates an arc. You can pass a 2 element vector to define the central angle. Its $fa, $fs and $fn parameters are consistent with the circle module.	arc(radius, angle[x,y], width);
archimedean_spiral	Gets all points and angles on the path of an archimedean spiral. The distance between two points is almost constant.	archimedean_spiral(arm_distance, init_angle, point_of_distance, num_of_points);
bend	Bends a 3D object into an arc shape.	bend(size = [x, y, z], angle) object();

Also, markdown supports triple-backtick code fencing which allows you to specify a language. With a proper language file, you can turn this

into this

by replacing the four-space with these: ```openscad

A cheat sheet is great and I might come up one when I have time.
