-/**
- * Perform sorting of enumerable collection with QuickSort algorithm.
- * Enumerable collection should provide the random access to its values
- * by index number with methods Value(theId) and ChangeValue(theId).
- * Currently it supposed to be used with NCollection_Sequence and NCollection_Vector.
- *
- * Usage sample:
- *   // input sequence
- *   NCollection_Sequence<Standard_Real> aSequence;
- *   // perform sorting for the whole sequence.
- *   NCollection_QuickSort<NCollection_Sequence<Standard_Real>, Standard_Real>
- *     ::Perform (aSequence, NCollection_Comparator<Standard_Real>(),
- *                1, aSequence.Size());
