Day 22: Reactor Reboot

Today's solution is a little weird...

I solved part one using the easy, store every point method. However, for part two, I didn't want to go to the trouble of writing code to work out the intersections of all the cubes. Instead, I chose to do the following:

Wrote some Python code (openscad-generate.py) to generate some OpenSCAD code based on the challenge input
- This made liberal use of nested union(), difference(), translate() and cube() functions
Ran this code in OpenSCAD and exported the resultant model as an STL
Imported this STL file into Blender and used the 3D-Print Toolbox addon to calculate the total volume of the object
Typed this number into the AoC website
Obtained the 2nd star ★ :D
