// The ChipEvent class stores the Location of the chip (and potentially
// channel) in a one two byte short variable as such
//
// CRATE     : 0-15 : 4 bits : Stored in 1:4 through 1:7
// VARC      : 0-3  : 2 bits : Stored in 1:2 through 1:3
// VMM       : 0-5  : 3 bits : Stored in 0:7 through 1:1
// VADC      : 0-1  : 1 bit  : Stored in 0:6
// VACHIP    : 0-2  : 2 bits : Stored in 0:4 through 0:5
// VACHANNEL : 0-15 : 4 bits : Stored in 0:0 through 0:3
//
//      Byte:           1              0
