a453f9d128 0028414: Data Exchange, STEP - Face on a closed surface with single inner wire and without natural bound not correctly read
Problem: From the point of view of the STEP format (and others), it is allowed
to describe a face on a surface with natural boundaries (torus, sphere) without
specifying these boundaries. Thus, a face on a closed surface and containing
an inner wire (or several) is correctly defined and describes a face with a
cutout defined by this wire. At the same time, there is a function
(ShapeFix_Face::FixOrientation) in the ShapeHealing procedure that corrects the
orientation of the wires, and it starts before the function of adding natural
boundaries (ShapeFix_Face::FixAddNaturalBound). There are many shapes that have
incorrectly oriented wires and this procedure successfully heals them, but on a
correctly specified face with single inner wire on closed surface, we do not get
the entire surface with a cutout, but a part of the surface defined by the wire.
This fix is intended to resolve this ambiguity.

Change:
1. Added function isNeedAddNaturalBound that returns TRUE if face needs to add
 natural bounds.
2. Corrected condition in FixOrientation to ignoring faces that needs to add
 natural bounds.
3. For tests in which one wire was incorrectly oriented on a closed surface,
flag AddNaturalBound was disabled.
5. Test with cutout from torus was created: bugs step bug28414.

Result: By default, it is correct to add natural boundaries, because this case
 is correct from the point of view of the STEP format and others.

51329afcef 0028024: Data Exchange - create a convenient mechanism for managing shape healing options when reading STEP or IGES file
Problem: There is no possibility to change shape healing options from DRAW without rewriting resource file.
Change: Shape healing parameters from STEP and IGES resource files were duplicated to InterfaceStatic. Resource manager initialize from InterfaceStatic if resource file name is empty.
Result: User can operationally change shape healing parameters from DRAW command using "param" command.

0029641: Mesher produce 'bad' result for extruded spline with given deviation coefficient

Added method BRepMesh_NURBSRangeSplitter::getUndefinedInterval() intended to compute checkpoint parameters for those NURBS surfaces which have no intervals at all. In this case number of poles is used to produce artificial regular grid which can be refined further. Add at least one midpoint for surfaces with one interval and only two poles.

Added BRepMesh_ExtrusionRangeSplitter and BRepMesh_UndefinedRangeSplitter derivatives from BRepMesh_NURBSRangeSplitter intended to handle special cases of extrusion surfaces and general surfaces with undefined parameters.

Test case de step_4 I1 has been marked BAD, because the self-intersection is treated correctly, but the projection algorithm generates such crooked 2D curve.
