// Class description:
// Example of analysis in a simulation application (histograms, ntuples etc.)
// This class follows the singleton design pattern; 
// it is responsible for the analysis management and algorithms 
// Histograms are compliant with AIDA 1.0 (the header files are
// copies from the Anaphe Interfaces directory), except for the usage of
// IHistoManager which is Anaphe/Lizard-specific
// For ntuples, for which the AIDA interfaces and compliant implementations
// are still in progress at the time of the current Geant4 release, 
// an implementation with Anaphe/Lizard is shown
// Other implementations specific to an analysis system are possible too
// (see, for instance, JAS and OpenScientist documentation from the links
// in http://aida.freehep.org/)
// The implementation of the usage of ntuples shown in this example
// is expected to change in future Geant4 releases, when AIDA interfaces 
// and related implementations would be available
// Further documentation is available from: http://www.ge.infn.it/geant4/lowE/
