*
* USAGE:
* var wf = webflash(options);
*
* Available options:
* id -> The id of the DOM node that acts as a container of
* the flash message. This element must exist in the DOM.
* Will default to "webflash" if missing from hash.
*
* name -> The name of the cookie that carries the payload.
* Will default to "webflash" if missing from hash.
*
* on_display -> (optional) Callback to execute after the flash message
* has been displayed. It is called with the payload
* and the container DOM node as first and second
* arguments.
* If this option is a string it is expected to be the
* name of a function attached to the window object
* create_node -> (optional) A function that should return the DOM node
* that will be appended to the container.
* If this option is a string it is expected to be the
* name of a function attached to the window object
*
* Available methods:
*
* wf.render() -> Renders the flash message stored in the flash cookie.
* This function must be called before the window has
* finisihed loading.
* If the cookie was not set by the server this is a noop.
*
* wf.payload() -> Returns an object with the payload stored in the cookie
* If no cookie was set returns null.
*
* Payload structure:
*
* The payload is expected to be an escaped JSON string which deserializes
* into an object with the following keys:
*
* message (string) -> The text to insert into the container. By default this
* text will be apended as a text node so HTML will be
* escaped. Initialize webflash with a custom
* 'create_node' function to override this.
* status (string) -> If present this will be the class of the div that
* holds the flash message inside the container.
* delay (int) -> If present, the flash container will be hidden after
* this amount of milliseconds.
*
* Extra arguments may be passed in th payload and interpreted by a custom
* create_node or on_display function.
*
