Class ListMap<K,V>

java.lang.Object
  org.semanticdesktop.aperture.util.ListMap<K,V>

public class ListMap<K,V>
extends Object

A Map like structure where each key maps to a list of values. I couldn't get the generics to work the way I wanted, so it doesn't inherit anything. TODO: move this to a utils project.
