	Doodle3D WifiBox firmware
	Web interface to draw doodles and print them with ease.
	Automatically connects to known network or provide one to connect with.
	Intended to be used on TP-Link WR703n or MR3020.

# In order to just build a simple program that we have just written, it is
# much easier to do it this way.
