all graph changes should be undo-able #209

Closed akissinger closed 5 years ago

akissinger commented 6 years ago

Currently some graph changes (e.g. minimise) do not register to the undo stack properly. This causes undefined behaviour (e.g. Null pointer exceptions) if you edit the graph some, minimise, then try to undo.
