    Goes to the indicated position. On RoboTel, we have two different slewing speeds available, which one we use depends on the distance we want to travel, decided by KEY_TRAVELFAST. Depending on the slewing speed chosen, we stop KEY_FASTPRE or KEY_SLOWPRE degrees before we reach the actual position. After the motor stopped moving, decided by #KEY_NOTMOVING, which is a value in degrees persecond, we check if we have reached the desired position within KEY_DESIREDOFF. If we are too far off, we are re-entrant into this method, but only to a certain depth of KEY_MAXRETRIES.
  - go
```
private boolean go(double to,
                   boolean forward,
                   boolean fast,
                   double within,
                   long timeout,
                   long cooldown)
```
    Goes to the indicated position, in the desired direction and speed. Starts the motor, starts a surveilance thread, and stops the motor.
  - getActualDomePosition
```
private double getActualDomePosition()
```
    Returns the actual dome position if the cache-time is over, otherwise the cached position is returned. If the driver is queried for a new position, the current one gets the last one. This information is then used to calculate the current speed.
  - getActualDomeVelocity
```
private Double getActualDomeVelocity()
```
    Checks the current and the last dome position and calculates a speed out of it, if both are valid, otherwise it returns null.
  - isMoving
```
private Boolean isMoving()
```
    We are moving, if our absolute speed is higher than the threshold.
  - createDomeReceiver
```
public static DomeReceiver createDomeReceiver(File props)
                                       throws IOException
```
    Creates a dome receiver, initalizes the dome driver and all parameters. Mainly for testing purposes.
    
    Throws:
    
    IOException
