/**
 * This class is used to see whether or not we should apply our security
 * Intercepter to a method.  In actuality, this class is a bit of a no-op
 * in the real application because RestEasy uses IsHttpMethod to pick up the
 * ResourceMethods that it will handle.  However, we need this matcher for testing
 * because we test with a AOP method intercepter which we don't want to apply
 * to just plain public/protected methods.  Also note that this matcher runs
 * on application deployment and not on every request.
