DAISY-1 - Daisy adapter for the FOX Board G20

Daisy is a cabling method reducing development time of equipment based on both FOX Board G20 and Netus G20 boards. The basic idea is to be able to wire on-field interfaces onto the NetusG20 module faster, using plugged instead of welded cables.

The DAISY-1 board is at the center of the Daisy cabling system. It is plugable over the NetusG20 board to provides 8 connectors to plug up to 8 or more daisy modules using ribbon flat cables.

Each connector is identified with a unique name as D1, D2, D3, etc. and has a different set of signals coming from the Atmel CPU.
