\brief H5Location is an abstract base class, added in version 1.8.12.
It provides a collection of wrappers for the C functions that take a
location identifier to specify the HDF5 object. The location identifier
can be either file, group, dataset, attribute, or named datatype.
Wrappers for H5A functions stay in H5Object.
