Initial version of interface 'CurveCreator_ISection' was created for the curve sections.

Browse Source 
Type 'CurveCreator_Section' was inherited from the interface and
extended to implement the interface.
Method 'CurveCreator_Curve::getSection' was modified for the interface.
Method 'CurveCreator_Utils::ConstructWire' was created to construct the wire corresponding to each polyline or spline section.
