 * This module will attempt to extract a bearer token from a request from these locations:
 * - The key access_token in the request body.
 * - The key access_token in the request params.
 * - The value from the header Authorization: Bearer <token>.
 * - Will check headers cookies if has any 'access_token=TOKEN;'
 * 
 * If a token is found, it will be stored on req.token. 
 * If a token has been provided in more than one location, the request will be aborted immediately with HTTP status code 400 (per RFC6750).
 * 
 * To change the variables used by this module, you can specify an object with new options.
