160416-27: Created.
...
170208: ArcCurve, PolyCurve, and Brep geometries now are made deformable when the
transform's SimilarityType is NotSimilarity, e.g., non-uniform scale.
180309: In response to V6 allowing objects to be added to reference layers,
option to retain the duplicated object's layer was added.
180926: Now, geometry from linked (not embedded) blocks will only be created on current layer.
...
230718: Now, block instances from references are placed on current layer.
230817: Modified some command option text.
231009: Bug fix for when BlockInstance is the target.
240629: Annotations are now skipped during search of lowest level picked geometry.
250120: Bug fix in command options.
TODO:
Point and TextDots require very accurate picking.
Possibly allow a distance tolerance for these objects.
Support adding BlockInstance of reference object.

ArcCurve is not supported by MakeDeformable.
