Code improvement

Description:
    - Moved class H5File to inherit from class Group because an HDF5 file is
      a root group
    - Cleanup header file inclusion and class forward declaration
    - Revised comments
Platforms tested:
    Linux/32 2.6 (jam)
    Linux/64 (platypus)
    Darwin (osx1010test)
