* @brief The ObjectIndicatorImpl can be used to ease the locating of an object.
|
|
* The ObjectIndicatorImpl can by parametrized with just the UniqueMapId to point to.
|
|
* update() will do the rest for you:
|
|
* - retrieve the object to point to,
|
|
* - get the bounding box of that object and
|
|
* - create an indicator from the current center of the map to the object.
|
|
* \note <b> If the object to point to disappears, you are responsible for removing the ObjectIndicatorImpl! </b>
