CPP: Manage state machine on a READ_WRITE attribute

To manage state machine on a READ_WRITE attribute, you need to modify the is_<attribute>_allowed method in the MyTangoClassStateMachine.cpp file like this:

bool MyTangoClass::is_Encoder_present_allowed(Tango::AttReqType type)
{
   if (get_state() == Tango::MOVING    ||
       get_state() == Tango::FAULT)
   {
       //    End of Generated Code

       if ( get_state()==Tango::MOVING && type==Tango::READ_REQ )
       {
           return true;
       }
       
       //    Re-Start of Generated Code
       return false;
   }
   return true;
}

This code checks if it is a read or write request and allow or disallow it.
