[svn-r30309] Purpose: Fix bug HDFFR-9920

Description:
    Rearranged the classes to model the relationship of HDF5 objects more
    accurately.  The changes included:
    - moved CommonFG's methods to Group
    - removed CommonFG from Group's base class list
    - removed CommonFG from H5File's base class list and changed
      "public H5Location" to "public Group" in the base class list
    - CommonFG became unused
    - result of the modified partial class diagram:

                                IdComponent
                                     |
                                H5Location
                                /
                        H5Object
                           |
                        /  /  \
                DadaType Group DataSet
                          |
                        H5File
Platforms tested:
    Linux/32 2.6 (jam)
    Linux/64 (platypus)
    Darwin (osx1010test)

-//	  can be added later when needed.

+// There are a few comments that are common to most of the functions
+// defined in this file so they are listed here.
+// - getLocId is called by all functions, that call a C API, to get
+//   the location id, which can be either a file id or a group id.
+//   This function is pure virtual and it's up to H5File and Group
+//   to call the right getId() - although, as the structure of the
+//   library at this time, getId() is basically the IdComponent::getId()
+//   ***Updated: after the classes are rearranged (HDFFV-9920), functions
+//		 in CommonFG are moved to Group, and they can call getId()
+//		 instead of getLocId().  getLocId() is kept for backward
+//		 compatibility on user applications.  Aug 18, 2016 -BMR
+// - when a failure returned by the C API, the functions will call
+//   throwException, which is a pure virtual function and is implemented
+//   by H5File to throw a FileIException and by Group to throw a
+//   GroupIException.
+//   ***Updated: after HDFFV-9920, methods in class Group use throwException
+//   to distinguish the FileIException and GroupIException.  CommonFG is no
+//   longer used in the library.  Aug 18, 2016 -BMR
