Out of Range - Takeoff

/* Title: Out of Range - Takeoff
 * Description:The Maglev can only take off if the flotor is in a position which can be detected by the devices sensors.
 * Usually, the monitor program is being used to check the sensors' status and to manually align the flotor so that it can
 * take off. This is rather inconvinient since it requires to start the monitor program everytime the flotor is out of range.
 *
 * The following code snippet shows an alternative method: It repeatedly checks the status of the Maglev sensors until
 * the flotor is in range of the sensors, then it will take off. If the flotor is out of range, a message will tell the user to
 * slowly move and rotate the flotor. As soon as the flotor gets in the range of the sensors, the code will initiate
 * a take off.
