               **************

 Put into histograms and into one ntuple the same physical
 information that has been extracted (and printed on
 screen) in the exercise  9_actions/ , that is the information
 relative to the calorimeter hits only.
 Use of  AIDA 3.0 / Anaphe 5.0.1 , and store the output 
 file in a HBOOK format.

 --- ANALYSIS class : where AIDA/Anaphe booking/filling/storing
     of the histograms and the ntuple are placed. 

     NB) This class should be the unique one which knows/depends 
         on the AIDA interfaces (which, anyhow, provide general
         interfaces independent from the actual analysis tool
         which is used afterwards to see the histograms and ntuple).

 --- EVENT ACTION : call the analysis methods to fill the histograms
     and the ntuple.

 --- RUN ACTION : call the analysis at the beginning of the Run
     to reset the histograms/ntuple of the eventual previous Run;
     call also the analysis at the end of the Run to commit the
     histograms/ntuple.
