CalcMotor: "state" method is calling "_calc_from_real".
CalcMotor "state" method is calling "_calc_from_real" method when state is ready.
This seems to be needed because pseudo motors position is not updated at the end of real motors movement. But:
1/ It prevents to use "state" method in calculation method of CalcMotor object (infinite recursion) and I need it.
2/ It seems to me that update of pseudo motors position at the end of real motors movement should be done in the movement sequence and not in the state, isn't it?
