 * 1) Interface in (Part::TopoShape) to robustly reference (name) shapes and sub-shapes (faces, edges, vertexes) through a string (sub-element name like "Face1") Here we need a interface to provide Part::TopoShape with all information need to do the Naming, e.g. NewShape, additional information from a algos like deleted faces, modeling step (for 2.) and ......
 * 2) Association of modeling steps with the resulting faces/edges. In case of a big model the user is lost if he/she has hundreds of fillets or bore hole. So if the faces/edges would know what modeling step  it created we could implement a double click on edge/face opens the right feature!
 * 3) An algorithm to keep the naming stable throughout changes in modeling history, like splitting edge/faces and moving vertexes [[File:NamingExample.jpg]]
 * 4) (optional) memory optimized data structure to keep only changed faces/edges in each modeling feature. This will become important when the models get bigger. Its not efficient to copy most of the shape just through. Would be much more effective to share the unchanged faces/edges between Feautures and copy only whats changed.
