vPiP hanging v-plotter control board Pi2/Pi3 add-on

This is my Raspberry Pi 2/3 add-on board for vPiP (Whats vPiP? Its a hanging v plotter control software written in Python and Arduino firmware - it can probably be used for other drawing machines, but its main purpose in life is for use with the vPiP software - https://github.com/brianinnes/vpip).

Update (29/04/2016): Will be continuing testing with the current crop of boards, but have moved master on github to v1.01b which adds a couple of minor fixes and features. Also created a Dev branch
