Class Description

 HDetParRootFileIo

 Interface class to ROOT file for parameter input/output
 Base class for all detectors

 This class is derived from the common base class HDetParIo
 for all inputs/outputs (ROOT file, Oracle, Ascii file).
 It contains all common functionality for all detectors which can be
 implemeted without knowing the exact type of the detector or of the detector
 dependend parameter containers using only the base class types.

 The data element modulesFound stores the indices of all modules in a
 detector which are are defined in the actual analysis which can be
 initialized from the ROOT file. If a detector cannot be found in the file
 this pointer is 0. The array ic created and filled via the function
 readModules(Text_t* detectorName) which is called when the first init()
 function of a parameter container belonging to this detector is called.

 The data element initModules stores the  indices of all modules for which a
 container has been initialized from the ROOT file.

 Constructor takes a pointer to the parameter ROOT file

 destructor

 reads the setup of the detector with given name from the ROOT file,
 compares it with the setup of this detector in the current analysis and
 creates and fills the data element modulesFound;
 Sets the flag isAktiv kTRUE.
 returns the number of modules not found;

 generic read function for parameter containers

 writes the setup of a detector to the ROOT file
 returns kFALSE if the file is not writable

 writes a parameter container to the ROOT file and returns the new version
 number (returns -1 if the file is not writable)

 returns the maximum version of the container given by name in the ROOT
 file (return -1 if not found)

 finds the input version to initialize the container given by name;
 returns -1 if the version cannot be determined

 finds the parameter container given by its name with a special version in
 the ROOT file (returns 0 if not successful)
 This funtion uses internally the ROOT function FindObject(Text_t*), which
 creates a new object. The calling function must therefore delete the
 object after usage!

 prints the module indices for which the container was initialized from
 the ROOT file (will later go to the log file)

 reads and fills the container for the basic geometry parameters of the
 detectors
