Synopsis

This class wraps a basic HDF5 object. It offers several benefits:

• The most important is resource management. In case of an exception, the object's hid will automatically be closed by the destructor.
• It acts as the base class for the basic objects file, group, and dataset.
• An HDF5 hid is a kind of pointer and should not be copied. These classes forbid making a copy, but make it possible to use them in a shared pointer context.
