Nearbysearch requires radius param

[vlazzle]

Sorry I didn't file an issue, I didn't think there was much to discuss here, but maybe I was wrong :P

Specifying location and radius params works: curl -L -X GET 'https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522%2C151.1957362&radius=1500&key=SOME_KEY'

But specifying only location doesn't: curl -L -X GET 'https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522%2C151.1957362&key=SOME_KEY'

[edit] I just noticed that radius is only required when not rankby isn't specified, or set to its default value of prominence. So omitting radius but setting rankby to distance works: curl -L -X GET 'https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=-33.8670522%2C151.1957362&rankby=distance&key=SOME_KEY'

Btw, by "doesn't work" I mean this response:

{
    "html_attributions": [],
    "results": [],
    "status": "INVALID_REQUEST"
}

Anyway, I'm not sure this PR is mergable any more, but I hope it's useful in getting to the bottom of this bug, whether it's in the documentation or behavior. Maybe it's just a matter of updating the nearby search developer guide.
