/**
 * StepMethodInterceptor that uses {@link MethodInterceptor} for intercepting JGiven methods
 * See below on how to configure this bean.
 *
 * 
 * Sample Configuration:
 * 
 * {@literal @}Bean
 * {@literal @}Scope("prototype")
 * public SpringStepMethodInterceptor springStepMethodInterceptor() {
 *     return new SpringStepMethodInterceptor();
 * }
 * 
 * 
 * The StepMethodInterceptor is stateful, and thus should use "prototype" scope
 * @since 0.8.0
