[Halld-tracking-hw] Grounding & Cabling

[Gerard Visser]

Hi Yves,
	I would think that the ground cable goes to a pin (or two) on the edge 
connector... I thought we had allowed for a ground pin in defining the 
pinout thereon?
	Anyway, another method is maybe ok if that is necessary. One ground 
wire/pin/socket per HVB, yes.
