* - ModuleSerialNumber.FunctionLogicalName
* - ModuleLogicalName.FunctionIdentifier
* - ModuleLogicalName.FunctionLogicalName
*
*
* This function does not require that the latitude sensor is online at the time
* it is invoked. The returned object is nevertheless valid.
* Use the method isOnline() to test if the latitude sensor is
* indeed online at a given time. In case of ambiguity when looking for
* a latitude sensor by logical name, no error is notified: the first instance
* found is returned. The search is performed first by hardware name,
* then by logical name.
*
* If a call to this object's is_online() method returns FALSE although
* you are certain that the matching device is plugged, make sure that you did
* call registerHub() at application initialization time.
*
* @param func : a string that uniquely characterizes the latitude sensor, for instance
* YGNSSMK2.latitude.
*
* @return a YLatitude object allowing you to drive the latitude sensor.
