 	 * It recursively collects all methods from super-classes and super-interfaces.

-	 * As of 5.3: Really all methods (incl. those of library super-classes

-	 *
-	 * Up to 5.2: The recursion stops when the super-type/super-interface is not in the model,
-	 * which means that no method of library super-classes, or of Object are present.
+	 * It includes the methods of types whose source code is in the Spoon model,
+	 * the methods of types from the JDK and from libraries present in the classpath,
+	 * the methods of java.lang.Object (for all CtClass objects).
+	 * However, in noclasspath mode, it does not include methods from unknown types.
+	 * If methods are overridden somewhere in the type hierarchy, it returns only top methods (ie method definitions).
+	 * Each method signature is returned only once
