//! This class provides services to compare sets of

//! a copy, acted by a CopyTool.

//! * Compare(...) compares two DataSet and returns
//! the result.
//!
//! * SourceUnbound(...) builds the difference between
//! a relocation dictionnary and a source set of
//! information.
//!
//! * TargetUnbound(...) does the same between a
//! relocation dictionnary and a target set of
//! information.
//!
//! * Cut(aDataSet, anLabel) removes a set of
//! attributes.
//!
//! * IsSelfContained(...) returns true if all the
//! labels of the attributes of the given DataSet are
//! descendant of the given label.
