Simple Support Module for OpenSCAD

MAKE SIMPLE POSTS TO SUPPORT YOUR PRINTS
=============
Overview:
--------
This is a very simple module that I use to quickly make little support beams from point A to point B, kind of like the ones in Meshmixer.

Meshmixer has been terrible for me lately so I decided to do support manually for some easy prints.

Give it two points and it makes a cylindrical post between them with cones on the ends.

Module Usage:
-------
`support( bot_pt , top_pt , dia = 0.6 , tip_dia = 0.36 , tip_h
