Class Description

  JSFModule

  Basic unit of data analysis

  User Analysis class should be derived from this class.
  Basic member functions for data analysis are,
      Initialize()
        BeginRun(Int_t RunNumber)
          Process(Int_t EventNumber)
        EndRun()
      Terminate()
  User class should override these functions.

  fFile is a pointer data member to the file.  It is set by JSFSteer
  and can be READ/WRITE/UPDATE. (UPDATE may not work properly yet.)
  Event data is stored in the tree, Event, in the "fFile".  Other
  configuration data are stored as an Keyed file in the "fFile".
  Directory and key names are,
       Initialize()  --> /conf/init/[modulename]
       BeginRun(nnn) --> /conf/beginNNNNNN/[modulename]
       EndRun(nnn)   --> /conf/endNNNNN/[modulename]
       Terminate()   --> /conf/term/[modulename]
  Note that key names have been changed since JSF-1-11, to
  simplfy the directory structure.
  The member function, ConfDirectory(), creates and cd to proper
  directory.  How to write/read data is depend on the implementaion
  of the class.
  Process is called only when the "fFile" is writable, while other
  functions are called evenif fFile is not writable.  If Initialize,
  BeginRun, EndRun, or Terminate is called when fFile is not writable,
  they should prepare data member of the class properly.

  Event data is saved in the object pointed by fEventBuf, which is
  the JSFEventBuf object.  JSFModule does not create JSFEventBuf.
  User class dereived from JSFModule should define fEventBuf.

  The member function, MakeBranch() and SetBranch() is called from
  JSFSteer::Initialize(). MakeBranch() defines the tree branch to
  store event data, while SetBranch() set addresses to read tree data.
  Usually, user read event data by tree->Fill(), which readin all branches
  in the tree. If the branch address is not set properly, the program will
  crash.  When reading the root data, JSFSteer  read the header and creats
  the objetcs required to get tree data.

 Default constructor of JSF module.

 Default constructor of JSF module.

 Set header information of event buffer.

 Find a pointer to the EventBuf objects in the same tree as this
 objects.
 Note that each EventBuf objects are saved as Branch of same tree.
