*   AliLHCData: summary of the LHC related information from LHC DIP.            *
*   Created from the TMap provided by the AliLHCReader with optional beginning  *
*                                                                               *
*   The data are (wrapped in the AliLHCDipValT):                                *
*   made of TimeStamp (double) and array of values                              *
*                                                                               *
*   Multiple entries for each type of data are possible. To obtaine number of   *
*   records (with distinct timestamp) for give type od records use:             *
*   int GetNBunchConfigMeasured(int beam) (with beam=0,1) etc.                  *
*                                                                               *
*   To get i-th entry, use brec= AliLHCDipValI* GetBunchConfigMeasured(bm,i);   *
*   Note: exact type of templated AliLHCDipValT pointer depends on the record   *
*   type, concult getters to know it.                                           *
*                                                                               *
*   Then, once the pointer is obtained, details can be accessed:                *
*   int nBunches = brec->GetSize();                                             *
*   for (int i=0;i<nBunches;i++) printf("Bunch#%d: %d\n",i,(*brec)[i]);         *
*                                                                               *
