/* This one's got:

     * converted to something closer to what is needed for the hardware version.
         * the code in the "classes" and "screen-related" tabs won't be included in the hardware version
         * any calls to functions starting with "screen" will be deleted or replaced. A comment on the line of the function will say if something should replace it.
         * the code in the "faux_buttons" tab needs to be replaced with functions that work with the hardware
         * calls to functions that start with "faux_" need to be replaced with hardware-valid functions
         * so
     * nodes, links, and a network to relate them
     * the updates for that network working
     * click party
     * illustrator import (limited)
     * better color, timing
     * center drawing
     
     Next:
     * one big question: how to manage the order of the nodes in the arrays?
