Execution
class ExecutionContext<State : Enum<State>, Event : Enum<Event>, GuardKey : Enum<GuardKey>, ActionKey : Enum<ActionKey>, Memento>
An ExecutionContext represents a running finite state machine. In order to execute a step, it maintains a reference to the executor, the current state, and a client-provided memento which will be passed as the sole argument of every action invocation.
To obtain a new execution context, a client should call StateMachine.createExecutionContext on an established FSM.
To execute a step, a client should call handleEvent with an appropriate event.
