squashable commit

not working construction of ArcOfHyperbola
Non-working stage:

To debug: Click the X icon in the sketcher and click 4 times with the left button (the parameters for creation of the hyperbola are hardcoded)

The CommandCreateGeo.cpp command for ArcOfHyperbola will jump to HyperbolaPyImp.cpp to
PyObject *HyperbolaPy::PyMake(struct _typeobject *, PyObject *, PyObject *)
Afterwards to:
int HyperbolaPy::PyInit(PyObject* args, PyObject* kwds)
Afterwards to file ArcOfHyperbolaPyImp.cpp:
PyObject *ArcOfHyperbolaPy::PyMake(struct _typeobject *, PyObject *, PyObject *)
to Geometry.cpp:
GeomArcOfHyperbola::GeomArcOfHyperbola()

Now I with kdevelop and gdb miss the lead:
1. It should go to the automatically generated outsource file ArcOfHyperbolaPy.cpp to the constructor (kdevelop fails to stop there)
2. It never gets to int ArcOfHyperbolaPy::PyInit(PyObject* args, PyObject* kwds), but I can not see where it stops, so I can not find why...
