Redo of the merge of Frame, RigidFrame, FixedFrame, Station and Marker ModelComponents along with code to convert Marker to new format for serialization/deserialization and inclusion of FrameSet in model.
@sherm1 @msdemers @aseth1 or @chrisdembia Please review and let us know your feedback.
@aseth1 I think you're looking at the removed code, the latest code removes and appends if name exists. The method Model::updateMarkerSet(aMarkerSet) is invoked from GenericModelMaker::processModel().
