[svn-r2897] Purpose:

	C++ API for 1.3.x branch

Description:
	The *.C and *.h files named different than those in 1.2.x.
	They are in the form: 'H5' + classname, or just classname if
	the classname is already prefixed with 'H5' to avoid ambiguity
	in documentation context.  This version has several hidden bugs
	fixed and an improvement on the reference counting approach.
	The classes and their inheritance structure are listed below:
	---------------------------------------
	H5Library
	Exception
	RefCounter
	IdComponent
		H5File
		DataSpace
		H5Object
			Group
			AbstractDs
				DataSet
				Attribute
			DataType
				PredType
				EnumType
				CompType
				AtomType
					StrType
					IntType
					FloatType
		PropList
			FileCreatPropList
			FileAccPropList
			DSetCreatPropList
			DSetMemXferPropList
	---------------------------------------
	IdComponent uses RefCounter to keep track of opened objects
	so proper termination of HDF5 objects can be maintained.
	Each class has a .h file containing the class declaration and
	a .C file containing its definition.  In addition to the classes
	files, the following files do not have class information:

	- H5Cpp.h: header file to be included in user's application
	- H5Idtemplates.h: contains a template function used by several classes
	- H5Classes.h: contains forward class declarations
	- H5CommonFG.*: contains common code used by classes H5File and Group
	- H5Include.h: contains the hdf5.h header file and the #undef RCSID
		to work around the problem: multiple defined RcsId
	- H5Alltypes.h: simply serves as a container to hold the header
		files of all datatypes to simplify the header file inclusion

Platforms:
	Solaris (arabica) and Linux
