Stars, Fractals, and Gears, this update's all about manipulating groups of GCodes to produce complex geometry!

This is probably about as spaghettified as I'm willing to let the code get-- next script update will finally be modularized into tidy packages. Scripts in the next pack will also be able to take command-line arguments.

para_07: Star. Demonstrates a list of GCodes, which can then be manipulated together.

para_08: The Koch Snowflake. Demonstrates a recursive function which draws a Koch Snowflake. This could be modified to construct a wide variety of 2D fractals. My algorithm isn't the cleanest version of this, however; a better one is on Wikipedia here:

para_09: Simple Gears. The gear script's a little beta-y right now but I decided to just post it as-is rather than let it hold up the script packs.
