ZMHW_Map/enclosure/README

For the enclosure, I put them on a wooden board, sand and finish the board with urethane, or some
other varnish, then mount the ZMHW shield, Mega, plus the Map on the wood. I then print this 
enclosure with a 3D printer, and use it to add some short circuit protection to the device
in a commercial environment. 

This current enclosure is for Rev 1, and as such, Rev 1 PCB has no fuse. 

Future revisions will add a fuse, and be smaller, at that.
