    //    the jQuery.param method.

    //    browsers that don't support window.postMessage.

    // 
    // Register a single callback for either a window.postMessage call, if
    // supported, or if unsupported, for any change in the current window
    // location.hash. If window.postMessage is supported and source_origin is
    // specified, the source window will be checked against this for maximum
    // security. If window.postMessage is unsupported, a polling loop will be
    // started to watch for changes to the location.hash.
    // 
    // Note that for simplicity's sake, only a single callback can be registered
    // at one time. Passing no params will unbind this event (or stop the polling
    // loop), and calling this method a second time with another callback will
    // unbind the event (or stop the polling loop) first, before binding the new
    // callback.
    // 
    // Also note that if window.postMessage is available, the optional
    // source_origin param will be used to test the event.origin property. From
    // the MDC window.postMessage docs: This string is the concatenation of the
    // protocol and "://", the host name if one exists, and ":" followed by a port
    // number if a port is present and differs from the default port for the given
    // protocol. Examples of typical origins are https://example.org (implying
    // port 443), http://example.net (implying port 80), and http://example.com:8080.

    //

    //

    //  callback - (Function) This callback will execute whenever a <jQuery.postMessage>
    //    message is received, provided the source_origin matches. If callback is
    //    omitted, any existing receiveMessage event bind or polling loop will be
    //    canceled.
    //  source_origin - (String) If window.postMessage is available and this value
    //    is not equal to the event.origin property, the callback will not be
    //    called.
    //  source_origin - (Function) If window.postMessage is available and this
    //    function returns false when passed the event.origin property, the
    //    callback will not be called.
    //  delay - (Number) An optional zero-or-greater delay in milliseconds at
    //    which the polling loop will execute (for browser that don't support
    //    window.postMessage). If omitted, defaults to 100.
