First off: thanks for your work on this, I am messing around w/ Instagram for fun right now, but have a few ideas for an app I want to develop.

I was kind of confused by the documentation. So I have my script (using express) logging in and getting a valid access_token. In my Instagram.oauth.ask_for_access_token callback I am setting the access_token as:
```
Instagram.set("access_token", params["access_token"]);
```
Then when I try to call Instagram.users.self() without any parameters, I get an error. I looked through the code and it looks like it should be defaulting to Instagram_config["access_token"] but it doesn't get that far - it gets to:

```
if ((require != null) && (params[require] != null) || (params['access_token'] != null) || (params['client_id'] != null)) {
return params;
}
```
(sorry, compiled - I'm not so much into CS yet)

And it dies on that line - here's the trace:
```
TypeError: Cannot read property 'access_token' of undefined

```

I am not sure if this is by design, but later you're checking for this._config['access_token'] so maybe a check if params === undefined is needed?

Anyhow, thanks again for your work.
