In ExRouter.js
##57: const Header = this.route.header;
##58: const header = Header ? <Header {...this.route.props} {...this.props}/> : null;
##60: const Footer = this.route.footer;
##61: const footer = Footer ? <Footer {...this.route.props} {...this.props}/> : null;
this.name can be a 'name' or '_name', so we will get double headers.
I will test the footer.
But thanks for ur nice work
