Function documents

• int GetRunNumber()
  Return fRunNumber.

• void SetRunNumber(int n)
  Assign n to fRunNumber.

• bool FileOpen(　const char* sourceName)
  Open file defined by sourceName. After opening the file, identify file type. If the file type is RIDF, create TArtRIDF::Instance().
  On the other hand, if the file type is RDF ( old data format in RIKEN), create TArtRDF::Instance().

• voidClose()
  Close sourceFile, and assign kNOTEXIST to fFileStatus.

• int Read(char *buf,const int &size, const int &offset)
  Read data from fFile. The data size is defined by size. And assign that buffer to buf.
  

• virtual int Seek(long offset, int origin)
  Seek fFile using offset and origin.
