Part: Enable trimmed curves to set their parameter range, from c++ and Python

=============================================================================

>>> geometries = ActiveSketch.Geometry
>>> geo2 = geometries[2]
>>> geo2
ArcOfCircle (Radius : 27.5267, Position : (-70.4702, -31.8933, 0), Direction : (0, 0, 1), Parameter : (1.34187, 2.35619))
>>> geo2.setParameterRange(1,3)
>>> geometries[2]=geo2
>>> ActiveSketch.Geometry=geometries
