Synopsis

This class wraps an HDF5 group hid (hdf5 id). It offers two benefits:

• The most important is resource management. In case of an exception, the hid will automatically be closed by the destructor.
• A hid is a kind of pointer and should not be copied. These classes make it possible to use them in a shared pointer.
