Obtains an OrderedMapIterator over the map.
A ordered map iterator is an efficient way of iterating over maps
in both directions.
BidiMap map = new TreeBidiMap();
MapIterator it = map.mapIterator();
while (it.hasNext()) {
Object key = it.next();
Object value = it.getValue();
it.setValue("newValue");
Object previousKey = it.previous();
}
