ExtrudeParams::elementMap possibly not cleared in DeMesh[GEntity]()
As usual, I am only possibly certain that this is a problem--but each time a user remeshes the geometry, the elementMap map in ExtrudeParams is not cleared by the deMeshGEntity functions. The map keeps growing with pointers pointing to deleted elements.
Incidentally, I discovered this because I am still working on a modification. I got the "hard crash" of referencing deleted object instances with outdated pointers.
