让 Go 便捷使用装饰器的工具，装饰器能够切面 (AOP)、代理 (Proxy) 任意的函数和方法，提供观察和控制函数的能力。go-decorator is a tool that allows Go to easily use decorators. The decorator can slice aspect (AOP) and proxy any function and method, providing the ability to observe and control functions.

增加装饰器参数

允许定义类似 func Logging(ctx *decor.Context, key string, autoBr bool) 这样的装饰器，可以额外传递参数给装饰器。

当方法返回值包含error类型时，执行报错

func (m *Demo) Run(a string, b string) (result string, err error) { result = fmt.Sprintf("%s %s", a, b) return }
报错：
`panic: interface conversion: interface is nil, not error

goroutine 1 [running]:
go-decorator-demo/demo.(*Demo).Run(0x9395a0, {0x84af04, 0x5}, {0x84af09, 0x5})
D:/GoProjects/go-decorator-demo/demo/demo.go:11 +0x27e
main.main()
D:/GoProjects/go-decorator-demo/main.go:10 +0x3c
exit status 2`

貌似在interface{}转换为error类型时发生错误，stackoverflow中有解决方案
