Curve Geometry
A Curve Geometry wraps a mathematical curve into a geometry for it to be able to be attached to an entity and added to a model to be renderable in a 3D scene and persisted with the model.
Curve Geometries are controlled via ICurveGeometry_DG interface.
A Curve Geometry can be created with a call IObjectGenerator_DG.Create("ICurveGeometry_DG").
