Next generic classes: "Contap_ArcFunction", "Contap_ContourGen", "Contap_HContToolGen", "Contap_HCurve2dToolGen", "Contap_Line", "Contap_Point", "Contap_SurfFunction", "Contap_SurfProps" from "Contap" package were converted to the non-generic classes. Names of several classes were changed: "Contap_Contour", "Contap_HContTool", "Contap_HCurve2dTool", "Contap_Line", "Contap_Point" Also all instantiations of the "internal" classes of this classes were moved to the "Contap.cdl". And sources of the "Contap_ContourGen" class were merged to one .cxx file.
