Class Description

 towerID

 The towerID class contains a tower ID number (encoding of detector
 element position) as well as functions to obtain the location of
 tower in question. TowerID is used in the CalHit class.


/________________________________________________________________________

 Create a towerID object with number tag

 Returns the tower number

 Sets the m_tag to tagVal

 theta bin in bits 3-11. Extract those bits, return them shifted down

 setTheta sets tag theta bits in appropriate place.

 phi bin in bits 12-20. Extract those bits, shift to "bottom", return

 setPhi sets tag phi bits in appropriate place

 phi bin width in bits 0-2. phiBinWidth extracts those bits.

 setPhiBinWidth sets tag phi bin width bits in appropriate place

 layer bin in bits 21-26. Extracts those bits, shift to bottom, return

 setLayer sets tag phi bits in appropriate place

 barrelEndcap in bit 30. Extract, shift to bottom and return.

 setBarrelEndcap sets tag barrelEndcap bit in appropriate place

 system in bits 28-29. Extract those bits, shift to bottom and return.

 setsystem sets tag system bits in appropriate place.

 north/south in bit 30. Extract, shift to bottom and return.

 setNorthSouth sets N/S bit in appropriate place.
