#99 Added echo integration, register a "path" directive that can work with echo router.

import httpin_integration "github.com/ggicci/httpin/integration"

func init() {
    e := echo.New()
    httpin_integration.UseEchoRouter("path", e)

    // or
    httpin_integration.UseEchoPathRouter(e)
}

Thanks
