Classes implementing this interface manage sets of resources. They support event notification on changes and are more heavy-weight than plain arrays or sets. For intermediate calculations that do not require events etc, consider using a {@link LightweightList} via {@link CollectionFactory}.

IMPLEMENTATION NOTE: This interface originally extended java.util.Set. However, the collection classes in java.util require supporting subclasses of Resource, as well as supporting generic objects in contains and remove. In GWT, this lead to a performance penalty, as instanceof checks and class casting are fairly expensive (at least according to profiling in Chrome 8). Therefore, this interface now provides methods that resemble the Java collections API, but are specific to Resources.
