Symbol (Akasha Java Browser API for J2CL)

```
@JsType(isNative=true,
        namespace="<global>",
        name="symbol")
public interface Symbol
```
The data type symbol is a primitive data type. The Symbol() function returns a value of type symbol, has static properties that expose several members of built-in objects, has static methods that expose the global symbol registry, and resembles a built-in object class, but is incomplete as a constructor because it does not support the syntax "new Symbol()".
