JsElem (json-values 0.1.2 API)

All Known Subinterfaces:

JsArray, JsNumber, JsObj, Json<T>

All Known Implementing Classes:

JsBigDec, JsBigInt, JsBool, JsDouble, JsInt, JsLong, JsNothing, JsNull, JsStr
```
public interface JsElem
```
Represents a json element of any type. Every json type implements this interface. This interface implements two kind of methods:
- Classificatory methods, which starts with the prefix isXXX
- Accessory methods to convert the JsElem to the real implementation, which starts with the prefix asJsXXX
