Preprocessor classes for SPD (Paul Nilsson)

*/

///////////////////////////////////////////////////////////////////////////
// AliITSChannelSPD implementation by P. Nilsson 2005
// AUTHOR/CONTACT: Paul.Nilsson@cern.ch
//
// Objects of this class are stored in TObjArrays and should be
// interpreted as "bad" channels, i.e. either noisy or dead channels
// depending on where they are stored.
//
// A channel has the structure:
//
//                           Int_t fColumn:    Column in the SPD module
//                           Int_t fRow:       Row in the SPD module
//
// The class is used by the AliITSPreprocessorSPD class to store noisy
// and dead channels in the calibration database for the SPD.
//
// A channel can be compared with other channels (the equality operator
// is defined). This is e.g. useful for the clustering algorithm. A noisy
// channel should not be used in the clustering
