27// MRawCrateArray
28//
29// This class exists to make it possible to read in the crate data
30// TClones Array. In principal we can directly write the TClonesArray
31// to the root file, but when we read in again the root file we cannot
32// put the TClonesArray into our parameter list, becaus it isn't derived
33// from MParContainer. This class is derived from MParContainer and can be
34// put in the list. The TClones Array containes conatiners which store
35// the information about one crate (MRawCrateData).
