 ## Data Decoder

 The data decoder is a function like `func(src []byte, dst map[string]interface{}) error`, which is used to decode the configration data from the data source.
 
 `Config` supports three kinds of decoders by default, such as `ini`, `json`, `yaml`, and `yml` is the alias of `yaml`. You can customize yourself decoder, then add it into `Config`, such as `Config.AddDecoder("type", NewCustomizedDecoder())`.
