HDF5 C++ Interfaces
===================
// HDF5 dataset and attribute have some common characteristics, so the
// term abstract dataset is used to name the element that can represent
// both objects, dataset and attribute.
//
// Class AbstractDs is an abstract base class, from which Attribute and
// DataSet inherit. It provides the services that are common to both
// Attribute and DataSet. It also inherits from H5Object and passes down
// the services that H5Object provides.

// Note that this datatype is a generic one and can only be accessed
// via generic member functions, i.e., member functions belong to
// DataType. To get specific datatype, i.e. EnumType, FloatType,
// etc..., use the specific functions, that follow, instead.
