Refactorings

[mogsie]

I'd love a tool like this to support various types of refactorings. An obvious one is "specialize" to introduce a substate; you might not even consider that a refactoring. But there are other types of refactorings that you could have like:

• Move transition to parent state — On a transition source, "move to parent state": The transition is moved to the parent state
• Move transition to substates — On a transition source, "move to substates": The transition is moved to all substates
• Introduce superstate: Select one or more states, and "Introduce superstate" — common transitions to and from the selected states are automatically placed on the new superstate
• Wrap in parallel state: Select one or more states, "Wrap in parallel state" — The states are wrapped in a region in a new parallel state, with another empty region alongside it.
• Introduce region: Select a state (with or without substates) — The state is converted to a parallel state with two regions, all existing substates are placed in one of the regions.

Opening this issue mainly to spark the discussion and get the ideas out there.

Thanks @mogsie. This is a great roadmap.
