/*! \class H5Object
\brief Class H5Object is a bridge between H5Location and DataSet, DataType,
and Group.
Modification:
Sept 18, 2012: Added class H5Location in between IdComponent and
H5Object. An H5File now inherits from H5Location. All HDF5
wrappers in H5Object are moved up to H5Location. H5Object
is left mostly empty for future wrappers that are only for
group, dataset, and named datatype. Note that the reason for
adding H5Location instead of simply moving H5File to be under
H5Object is H5File is not an HDF5 object, and renaming H5Object
to H5Location will risk breaking user applications. -BMR
Apr 2, 2014: Added wrapper getObjName for H5Iget_name -BMR
