NIST RS274/NGC

"Hello World" brought to you by NIST RS274/NGC (aka gcode), python3, and maybe a little too much free time https://github.com/grwhitehead/rs274ngc-python3

Also, this was my first time using @the_antlr_guy's ANTLR parser generator. Pretty slick! https://www.antlr.org

My favorite part of this project was realizing that you can abuse @openscad to turn gcode back into a 3d model ;-)
