/**
 * The root class, holding our links to NativeCollections and GSCollections.
 * NativeCollections tests native accessors, and throws exceptions when non-native
 * accessors are used.
 * GSCollections does the same, in reverse - if natives are used, it will throw
 * exceptions.
 * 
 * All classes have a minefield of other methods that shouldn't ever get called; if any
 * of them do, an immediate exception will be thrown.
