/**
 * Returns the set of all non-private methods from {@code type}, including methods that it
 * inherits from its ancestors. Inherited methods that are overridden are not included in the
 * result. So if {@code type} defines {@code public String toString()}, the returned set will
 * contain that method, but not the {@code toString()} method defined by {@code Object}.
 * <p/>
 * <p>The returned set may contain more than one method with the same signature, if
 * {@code type} inherits those methods from different ancestors. For example, if it
 * inherits from unrelated interfaces {@code One} and {@code Two} which each define
 * {@code void foo();}, and if it does not itself override the {@code foo()} method,
 * then both {@code One.foo()} and {@code Two.foo()} will be in the returned set.
 *
 * @param type         the type whose own and inherited methods are to be returned
 * @param elementUtils an {@link Elements} object, typically returned by
 *                     {@link javax.annotation.processing.AbstractProcessor#processingEnv processingEnv}<!--
