////////////////////////////////////////////////////////////////////////
//  Map Class for ITS. Implementation A2. In this implementation, the //
// 2 dimensional (iz,ix) map is filled with Double precision floating //
// point values. For each cell a corresponding TObject, a hit, can    //
// also be stored. This class is derived from AliITSMapA1 so that is  //
// retains all of the functionality of that map class as well.        //
