Fixed not working examples.

FayFromJs still not working at 100% and outputs:
```
aVector = {"x":1,"y":2}
|aVector| = 2.23606797749979
|[10, 20]| = 22.360679774997898
aVector + [10, 20] = {"x":{"forced":false},"y":{"forced":false}}
aVector + [10, 20] = {"x":{"forced":false},"y":{"forced":false}}
```

{"forced":false} is unevaluated lazy value. Possible solitions: allow struct data structures or override toJSON() function of object.
