========================================
When writting solver implementations it has to be taken into account that the normal is not to be provided in the sense of the curvature, but to
the left when walking a curve from start to end.

This commit has impact on all the previous files using bspline and endpoint to endpoint tangency.
A work-around is to delete the tangency and do it again.
=====================================================================================
Support for tangency/perpendicularity using angle via point for BSpline with appropriate
endpoint multiplicity so that the endpoints goes thru the first and last poles (control points).
Warning: Not applicable to periodic BSplines.
Warning: Not applicable to any non-periodic BSpline with inappropriate endpoint conditions.
=============================================
multiplicities, degree and periodic are left as non-parameters of the solver, while still allowing certain manipulations to be effected from the solver
in certain situations (for example modifying the multiplicity of start/end nodes when applying G1,G2,G3 constraints between BSplines).
- Fixing Hyperbola classes to get CCW emulation (like Ellipse classes).
In Sketcher:
- The Sketcher representation deals with the right branch of the Hyperbola only.
- Solver model is: Center, Focus1 (focus of the right branch), minor radius (b).
- HyperbolicArcRangeToEndPoints code is the one of Ellipse <= Awaiting DeepSOIC help ;)
- ConstraintPointOnHyperbola solver constraint is now implemented and should be working.
- No InternalAligment constraints implemented yet.
===============================================
- ArcOfHyperbola creation method
- Solver representation (undefined moving)
- SketchObjectPyImp (here we still miss the Part->Partdesign conversion)
- Sketch validation for hyperbola
- Hyperbola creation method: shows the "proof of concept", but it is very buggy!!
Notes:
- Missing icons, probably missing geo normal curve implementation - rebasing -
- Fixes to adapt Hyperbola to Derivector implementation and make it compile
