Change Log for the Are You A Human PHP Integration Library

1.1.4: 09/24/2012:
    - refactored __load_config_file() to not use __DIR__ because it is not supported in PHP
      versions prior to 5.3.0.

1.1.3: 09/12/2012:
    - fixed typo in debug message that prevented a debug value from displaying.
    - added a note about "Lightbox" to the header of the sample.php file.

1.1.2: 08/28/2012:
    - added the __load_config_file() function and refactored __construct() to use it.
        - this function looks for the ayah_config.php file in two places:
            1) the current directory
            2) the directory where the ayah.php file resides
    - refactored __log() to store messages into a buffer if debug mode is not on.
    - added the __flush_message_buffer() function and refactored debug_mode() to use it.
    - added log messages to show the current publisher key, scoring key and AYAH webservice hots.

1.1.1: 08/09/2012:
    - moved code that includes ayah_config.php into __construct() and log a debug message if not found.
    - added code to getPublisherHTML() to check that site is able to connect to AYAH webservice.
    - added code to getPublisherHTML() to support setting runtime options.
    - fixed minor bug in doHttpsPost()

1.1.0: 07/25/2012:
    - added public functions:
        - debug_mode()

    - minor refactoring to several routines to make them easier to read/maintain.

1.0.2: 03/21/2012:
    - Changed the script tag to include language="JavaScript" and type="text/javascript" for maximum compatibility.

1.0.1: 12/12/2011:
    - Add fallback support for JSON decode with Michal Migurski's library
