Class Description

 LCDTkID

 The TkID class contains a binary ID number and functions to obtain
 the location of the hit in question.  The TkID class is used in the
 Tracker_Hit and VXD_Hit classes.

void SetLayer(UInt_t tag)

 SetLayer sets the first 8 bits of m_tag to the layer number
Int_t layerShift = tag & LCDTkID::layerOn;

UInt_t GetNorthSouth() const

 north/south in bit 30. northSouth extracts that, returns
 it shifted down to least-significant end.

void SetNorthSouth(UInt_t tag)

 SetNorthSouth sets tag N/S bit (bit 30) to requested value.

UInt_t GetBarrelEndcap() const

 barrelEndcap in bit 31. BarrelEndcap extracts that bit
 and shifts to least-significant end.

void SetBarrelEndcap(UInt_t tag)

 SetBarrelEndcap sets  barrelEndcap bit (bit 31) to requested
 value

void SetSystem(UInt_t tag)

 SetSystem sets tag system bits in appropriate place (bits 28-29)
