*
* api_key is the API key, also known as the OAuth consumer key

*
* Both the api_key and shared_secret are generally provided by the site
* offering OAuth services. You need to specify them at object creation
* because nobody <explative>ing uses OAuth without that minimal set of
* signatures.
*
* If you want to use the higher order security that comes from the
* OAuth token (sorry, I don't provide the functions to fetch that because
* sites aren't horribly consistent about how they offer that), you need to
* pass those in either with .signatures() or as an argument to the
* .sign() or .getHeaderString() functions.
*
* Example:
<code>
var oauthObject = OAuthSimple().sign({path:'http://example.com/rest/',
parameters: 'foo=bar&gorp=banana',
signatures:{
api_key:'12345abcd',
shared_secret:'xyz-5309'
}});
document.getElementById('someLink').href=oauthObject.signed_url;
</code>
*
* that will sign as a "GET" using "SHA1-MAC" the url. If you need more than
