    Get the non-destructive path (if any exist) that is the shortest sequence of Transitions required to migrate from startState to endState.

    Get the non-destructive path (if any exist) that is the shortest sequence of Transitions required to migrate from startState to endState. NOTE: If there exists more than one shortest non-destructive path, then one of them is arbitrarily returned.

    startState

    state for path to start from

    endState

    state for path to end at

    returns

    Some non-destructive sequence of Transitions from startState to endState, or None if there is no such path; if startState == endState then returns an empty sequence.
