// Filename : TileCell.h
// Author   : Ed Frank, Ambreesh Gupta
//          : University of Chicago
//
//
// DESCRIPTION:
//    A TileCell is a CaloCell, the latter representing the basic observation
// in the Atlas calorimeters:  An energy, position, time and quality.  A
// CaloCell has been calibrated so that energy() returns the physical energy
// deposit _in the cell_ with units of MeV, but without any kind of
// leakage corrections.  Time represents when the feature extraction thinks
// the deposit occured, in nanoseconds, relative to the trigger.  It ought
// to be zero for good hits.
// Quality is an 32-bits integer number, which is split in 4 unsigned chars
// m_tileQual[4] like this:
//   m_tileQual[0] and m_tileQual[1] are  unsigned quality from TileRawChannel for first and second PMT
//   m_tileQual[2] and m_tileQual[3] contains special bits for first and second PMT respectively:
//     bit [0-2] -  the algorithm used to reconstruct given channel
//                  (one of TileFragHash::TYPE)
//     bit 3      - the channel is marked as bad in COOL DB
//     bit 4      - signal overflow detected in ADC samples
//     bit 5      - amplitude is large enough so that time will be saved in ESD
//     bit 6      - TileCell was read from Compact CaloCellContainer
//     bit 7      - TileCell contains non-zero time
//
//
// HISTORY:
//    nnFeb00  Created by Ambreesh
//    24Jan01  Made to inherit from CaloCell.  This breaks TileG3Cell.
//
//    12June02 [Zhifang Wu] Completely changed.  Remove duplicate variable definitions caused by improper inheritance.
//    14June02 [FSM] remove constructors taking (eta, phi) or (x,y,z).  Only allow stantard constructor, default.
//    16July04 [ALupi] new constructor added for Cells created from TileBeamElems
//    25Aug04  [Solodkov] timeDiff added
//    20Oct04  [Solodkov] new approach for quality
//
//    20-May-2008 [Solodkov] migrating to floats
//    20-Jul-2008 [Solodkov] store quality in unit8 quality[4] array
//
// BUGS:
