window.alert & window.confirm are ugly non-customizable. They are also blocking so that no JavaScript can be run while the dialog is present.

Dialog.js tries to solve this with a HTML-based dialog with customizable buttons and text. It's simple, easy to use, and lightweight.

Dialog.js will work on its own without any dependencies, but if you include clickable.js before it buttons will automatically perform better and will get native-like downstates.

Dialog({
	title   : 'This is a title!' ,
	text    : 'This is some text to tell the user what is happening and what to do.' ,
	success : 'Ok' ,
	cancel  : 'Cancel' ,
}, function (status) {
	if (status) {
		// user clicked the success button
	}
	else {
		// user clicked the cancel button
	}
});

If a dialog is already open when another is called, it will be queued and launched immediately after the previous one is resolved.
