//! This class provides services to build, copy or
//! paste a set of information.
//!
//! Copy methods:
//! -------------
//!
//! * Copy(aSourceDataSet, aTargetLabel,
//! aRelocationTable) copies a source DataSet under
//! its target place (see below: IMPORTANT NOTICE 1).
//!
//! * Copy(aSourceDataSet, anTargetLabel,
//! aRelocationTable, aFilter) does the same job as
//! the previous method. But <aFilter> gives a list of
//! IDs for which a target attribute prevails over a
//! source one. In this special case, the source
//! attribute will be copied only if there will be no
//! target attribute.
//!
//! IMPORTANT NOTICE : Label pre-binding
//! ------------------
//!
//! For it is possible to copy root labels in another
//! place in the same Data or in a different one with
//! other tags, it is necessary to inform the Copy
//! algorithm about the target place. To do so:
//!
//! * first get or create new target root labels;
//!
//! * then bind them with the source root labels using
//! the relocation table method:
//! SetRelocation(aSourceLabel, aTargetLabel);
//!
//! * finally call Copy(...) with the relocation table
//! previously set. In this way, this method will take
//! these relocations in account.
