Any number of options can be specified, and duplicate keys in queryParams are overwritten with new values.  This makes it possible to initialize the widget like this:

`fbopenWidget.initWidget({q: 'new search term'});`

or like this

```
fbopenWidget.initWidget({
    q: 'new search term',
    api_key: 'NEW_API_KEY',
    open_search_enabled: false
});
```

Both are equally valid.  New options will merge with the old, and overwrite any conflicting values.
