/**
 * ATransformation is an "abstract Transformation" -- it's an implementation of the Transformation
 * interface, that automatically fills in the two typing methods.  As such, it's useful for 
 * extending as an anonymous inline class (i.e.
 * <code>
 * Transformation<Foo,Bar> t = new ATransformation<Foo,Bar>(Foo.class, Bar.class) { 
 * 	public Bar transform (Foo a) { 
 * 		...
 * 	}
 * };
 * </code>
