Parametric Support tree

A perl script to create a .scad file for a support tree.

You need to input the spread for X and Y, and a formula for the height at each point.

The tree build is not optimal in either material or vertical space.

Known bugs: For large trees, especially if the height of the support points are not the same, it builds several sub trees. I do not have the time to find and correct this bug at the time being, so use with care, and manually add the branches needed.
