Added example for iterating over simple array.

[dzeban]

It's not clear from documentation how to iterate over scalar arrays (not an array of objects, e.g. like in example). _WJEString, _WJEInt32 which are intended to be "handy" on iterating over multiple elements are actually confusing since last argument has type WJElement. After struggling for an hour I've come up with a solution where you invoke WJEGet and then pull the value via "." selector. This is what this pull request demonstrate.

Maybe it's not the way someone should do this, but then, please, correct me and we'll update the documentation accordingly because as I said it's really confusing.

P.S. I haven't seen a "Firefly" and it was hard for me to come up with an appropriate example, so I would be glad if you suggest a better one.

Nice! That's a good idea, I'll probably include this as-is and update the javascript side of the example to match.

Great! But still - am I right that using WJEGet and "." or empty selector is a supposed way to iterate over array of scalars?

[penduin]

I applied and fixed up your patch a bit. You were appending empty objects {} to the element and then replacing them with strings; the example now just appends strings.

And yes, WJEGet and then WJEString et al with an empty selector or "." (or, as I did it, NULL) returns the value for the current element.

Thanks again, and... I really really need to add more examples, don't I? :^)

Thanks, looks great! As for examples - it's never enough ;-)
