    15    * The Ajax framework, via the ajax_deliver() and ajax_render() functions,
       
    16    * returns an array of commands. This array sometimes includes commands
       
    17    * automatically provided by the framework in addition to commands returned by
       
    18    * a particular page callback. During testing, we're usually interested that a
       
    19    * particular command is present, and don't care whether other commands
       
    20    * precede or follow the one we're interested in. Additionally, the command
       
    21    * we're interested in may include additional data that we're not interested
       
    22    * in. Therefore, this function simply asserts that one of the commands in
       
    23    * $haystack contains all of the keys and values in $needle. Furthermore, if

    25    * that all keys and values within that array are present in the command we're
