0024734: Convertation of the generic classes to the non-generic. Part 4
Generic classes "LProp_FuncCurExt", "LProp_FuncCurNul" and "LProp_NumericCurInf" from "LProp" package converted to the non-generic classes and moved to the "Geom2dLProp" package. Therefore names of this classes were changed to "Geom2dLProp_FuncCurExt", "Geom2dLProp_FuncCurNul" and "Geom2dLProp_NumericCurInf". Generic class "Sweep_LinearRegularSweep" from "Sweep" package converted to the non-generic classes and moved to the "BRepSweep" package. Therefore name of this class was changed to "BRepSweep_NumLinearRegularSweep". Also 2 internal classes of "BRepSweep_NumLinearRegularSweep" moved to "BRepSweep.cdl". Generic classes "Primitives_Wedge" and "Primitives_OneAxis" from "Primitives" package converted to the non-generic classes and moved to the "BRepPrim" package. Therefore names of this classes were changed to "BRepPrim_GWedge" and "BRepPrim_OneAxis". Also enum "Direction" moved to BRepPrim. Therefore all "Primitives" package was deleted. And some other minor changes were done. Internal classes Array2OfShapes and SequenceOfShapes from BRepSweep_NumLinearRegularSweep replaced to Array2OfShape and SequenceOfShape from TopTools.
