Class Description

 HParRootFileIo

 Interface class for parameter I/O from/to ROOT file
 derived from interface base class HParIo.

 It contains a pointer to the "connection class" of type HParRootFile
 inherited from TFile.  HParRootFile contains an object of type HRun
 which holds the list of container versions for an event file.

 It contains also a list of detector interface classes all having the common
 base type HDetParRootFileIo. Every detector has its own interface class.

 This class replaces the former class HParFileIo.

 constructor

 destructor closes an open file

 It opens a ROOT file (default option "READ"). An open file will be closed.
 The detector I/Os for all detectors defined in the setup are activated.

 closes an open ROOT file and deletes the detector I/Os

 prints the content of a open ROOT file and the list of detector I/Os

 returns a pointer to the current ROOT file

 reads the parameter container versions for the current run from
 the ROOT file

 returns the list of keys found in the ROOT file
