Dr. Jones can make several design suggestions even for this seemingly straightforward refactoring.
	If the method is polymorphic in the source hierarchy, it’s likely that the programmer will want to express that polymorphism on the target hierarchy.
	So we leave to-dos for the programmer to move the overriding and overridden methods to appropriate places in the target hierarchy.
	Also, if the method is overloaded with functions of the same name but different signatures, then the programmer might want to move those as well.
	Finally, if the method uses fields or methods in the source class, the programmer will need to provide access to them (I.e., by encapsulating those fields).
