8// Map Class for ITS. Implementation A2. In this implementation, the //
9// 2 dimensional (iz,ix) map is filled with Double precision floating //
10// point values. For each cell a corresponding TObject, a hit, can //
11// also be stored. This class is derived from AliITSMapA1 so that is //
12// retains all of the functionality of that map class as well. //
