-/**
- * This extension of PropertyAdapter provides TreeChange support.
- * This allows us to convert a set of one or more trees into
- * a single tree, NODES.
- * 
- * The typical subclass will override the following methods:
- * #nodes_()
- *     at the very minimum, override this method to return an iterator
- *     on the subject's tree aspect; it does not need to be overridden if
- *     #nodes() is overridden and its behavior changed
- * #nodes()
- *     override this method only if returning an empty iterator when the
- *     subject is null is unacceptable
