Class Description

  JSFDBS

  Base class to use data base in the JSF

  The name of the data base file is obtained from the environment
  variable, JSFDBS.FileName.  The default name is "jsfdbs.root".
  As a default, the file is opened by READONLY mode.
  To WRITE to the data base, open by yourself with WRITE mode,
  set tell its file name by SetFile(file).  Nomal procedure will be

   TFile *f= new TFile("mydbs.root") ;
   JSFDBS::SetFile(f);
   MyDBS *d=new MyDBS(data.....)

  Run number is a key of the data base.
  If run > 0, read data when this object is created.
  If run <= 0, create the object with empty data.
  Use this option, when you write to the data base file.

  Open Data base.
