Part: Rearrange inheritance not to use ArcPy

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

Inheritance:

Geometry
- GeomPoint
- GeomCurve (GeometryCurvePy)
- - GeomBoundedCurve (BoundedCurvePy)
- - - GeomBezierCurve (BezierCurvePy)
- - - GeomBSplineCurve (BSplineCurvePy)
- - - GeomTrimmedCurve (TrimmedCurvePy)
- - - - GeomArcOfConic (ArcOfConicPy)
- - - - - GeomArcOfCircle (ArcOfCirclePy)
- - - - - GeomArcOfEllipse (ArcOfEllipsePy)
- - - - - GeomArcOfHyperbola (ArcOfHyperbolaPy)
- - - - - GeomArcOfParabola (ArcOfParabolaPy)
- - - - GeomLineSegment (LineSegmentPy)
- - GeomConic
- - - GeomCircle
- - - GeomEllipse
- - - GeomHyperbola
- - - GeomParabola
- - GeomLine
- - GeomOffsetCurve

* Note: ArcPy is also a twinclass of c++ GeomTrimmedCurve, Python ArcPy derives from Python TrimmedCurvePy.

Same functionality as before:

>>> geometries = ActiveSketch.Geometry
>>> line = geometries[1]
>>> arc = geometries[2]
>>> line
<Line segment (-97.4389,42.4463,0) (-80.7887,44.5569,0) >
>>> arc
ArcOfCircle (Radius : 19.3111, Position : (-74.6914, -23.2165, 0), Direction : (0, 0, 1), Parameter : (1.82335, 2.71597))
>>> line.FirstParameter
0.0
>>> line.LastParameter
16.783437032695776
>>> line.setParameterRange(0,20)
>>> line.LastParameter
20.0
>>> arc.StartPoint
Vector (-79.51683708894876, -4.517938119394778, 0.0)
>>> arc.EndPoint
Vector (-92.27963885411512, -15.243140671641918, 0.0)
>>> arc.setParameterRange(1.5,3)
>>> arc
ArcOfCircle (Radius : 19.3111, Position : (-74.6914, -23.2165, 0), Direction : (0, 0, 1), Parameter : (1.5, 3))
>>> geometries[1] = line
>>> geometries[2] = arc
>>> ActiveSketch.Geometry = geometries
>>> ActiveSketch.solve()
0
