示例1: bindToMapBidirectionally

* value will be set to null.

* @param property the property to bind
* @param map the map to bind to
* @param key the key for the entry to bind to
* @param v2t a conversion function for converting objects of type <i>V</i> to type <i>T</i>
* @param <K> the types of the keys in the map
* @param <V> the types of the values in the map
* @param <T> the type of data in the property
