> At the moment, every implementation of {{ExecutionPhaseHandler}}, apart of
> logic dedicated to that particular case, contains and logic of transition
> from current phase to next one. Beside, {{Query}} object, which supposed to
> be a container enclosing state, has method {{run}} which in fact is main loop
> of the FSM.
> To make code cleaner, let's introduce concept of execution program. Program
> is an object describing transition graph. Also, main loop of FSM execution
> must be enclosed in the program. When query reaches the terminal state
> defined by the program, the program execution must return a result.
