 * Modified by Dongsheng Cai <dongsheng@moodle.com>

 * ChangeLog:

 *   1. Remove PEAR HTTP LIB, use curl.class.php (created by myself)

 *   2. Remove PEAR DB LIB

 *   3. Remove all cache code, it will implement in curl class.

 *   4. Clean up session code

 *

 * Modified by David Mudrak <david@moodle.com>

 * ChangeLog:

 *   1. upload() method uses Moodle stored_file

 *   2. upload() method supports all params provided by http://www.flickr.com/services/api/upload.api.html

 *   3. auth() method shows debugging warning as this library cannot be used any

 *      more for calling Flickr API that requires authentication.
