 * This provides a bunch of Java like classes.  Collections, HashMap, HashSet
 * and a few conviences.   Attention has been paid to make it look very
 * similar, however they are not identically. Specifically "size" is not a function
 * it still a property.   This is mostly due to fear, of what will break if we change
 * that value.
 *
 * It should be useful for Java programmers coming to JS and for porting code from JS->JavaScript
 *
 * These classes are meant to be convient hence iteration.
