### Marshaling
### Unmarshaling
You also have the option of Marshaling all or a specific value to a struct, map,
You also have the option of Unmarshaling all or a specific value to a struct, map,
etc.
There are two methods to do this:
* `Marshal(rawVal interface{}) : error`
* `MarshalKey(key string, rawVal interface{}) : error`
* `Unmarshal(rawVal interface{}) : error`
* `UnmarshalKey(key string, rawVal interface{}) : error`
Example:
