(:~ A library module for signing and submitting OAuth requests such as the kind needed for the Twitter v1.1 API.

    The EXPath Crypto library supplies the HMAC-SHA1 algorithm. The EXPath HTTP Client library makes the HTTP requests.
    The OAuth standard requires a "nonce" parameter - a random string.  Since there is no implementation-independent
    nonce function in XQuery, we must rely on implementation-specific functions.  For eXist-db we use util:uuid().

 : Works well with edited text like newspapers. Parameters like punctuation can/should be edited;
