Type	Function
Description	Displays a simple non-blocking dialog box using `NSAlert` and a hidden `hs.webview` that's automatically destroyed when the alert is closed.
Parameters	x - A number containing the horizontal co-ordinate of the top-left point of the dialog box. Defaults to 1. y - A number containing the vertical co-ordinate of the top-left point of the dialog box. Defaults to 1. callbackFn - The callback function that's called when a button is pressed. message - The message text to display. [informativeText] - Optional informative text to display.

If `nil` is used, no second button will be displayed. [style] - An optional style of the dialog box as a string. Defaults to "warning".

If something other than these string values is given, it will use "informational". Example: `lua</li><li> testCallbackFn = function(result) print("Callback Result: " .. result) end</li><li> hs.dialog.alert(100, 100, testCallbackFn, "Message", "Informative Text", "Button One", "Button Two", "NSCriticalAlertStyle")</li><li> hs.dialog.alert(200, 200, testCallbackFn, "Message", "Informative Text", "Single Button")`
