Class Description

                                                            
 BrGeantData provides an interface to GBRAHMS output       
                                                            

  Constructor. Set fFilePointer and fEventCounter to NULL

 Constructor. Set fFilePointer and fEventCounter to NULL
 and open the file pointed to by *filename. Open also
 reads the file header.
 This is a problem. A constructor cannot return a type and thus not
 assign any reasonable value.

 Open the ASCII data file *fname. Returns kFALSE
 if the file can't be opened.
 Otherwise the fFileName data member is set to the
 corresponding filepointer. The file header is read

 Close the file pointed to by fFilePointer. Returns
 kFALSE if no file was open.

 Reads one event from the stream i/o data file. A BrEvent
 object is created and the hitlist and tracklist for
 this object is filled with data read from the file.

 Releasing the memory for this event is the responsibility
 of the function/macro calling GetNextEvent()
 The memory
 is completely released by a call to the BrEvent destructor
 (e.g. delete event;)
