		//2 - if they are different, copy `data` to `cached` and update the DOM
		//    based on what the difference is
		//3 - recursively apply this algorithm for every array and for the
		//    children of every virtual element

		//the `cached` data structure is essentially the same as the previous
		//redraw's `data` data structure, with a few additions:
		//- `cached` always has a property called `nodes`, which is a list of
		//   DOM elements that correspond to the data represented by the
		//   respective virtual element
		//- in order to support attaching `nodes` as a property of `cached`,
		//   `cached` is *always* a non-primitive object, i.e. if the data was
		//   a string, then cached is a String instance. If data was `null` or
		//   `undefined`, cached is `new String("")`
		//- `cached also has a `configContext` property, which is the state
		//   storage object exposed by config(element, isInitialized, context)
		//- when `cached` is an Object, it represents a virtual element; when
		//   it's an Array, it represents a list of elements; when it's a
		//   String, Number or Boolean, it represents a text node

		//`parentElement` is a DOM element used for W3C DOM API calls
		//`parentTag` is only used for handling a corner case for textarea
		//values
		//`parentCache` is used to remove nodes in some multi-node cases
		//`parentIndex` and `index` are used to figure out the offset of nodes.
		//They're artifacts from before arrays started being flattened and are
		//likely refactorable
		//`data` and `cached` are, respectively, the new and old nodes being
		//diffed
		//`shouldReattach` is a flag indicating whether a parent node was
		//recreated (if so, and if this node is reused, then this node must
		//reattach itself to the new parent)
		//`editable` is a flag that indicates whether an ancestor is
		//contenteditable
		//`namespace` indicates the closest HTML namespace as it cascades down
		//from an ancestor
		//`configs` is a list of config functions to run after the topmost
		//`build` call finishes running

		//there's logic that relies on the assumption that null and undefined
		//data are equivalent to empty strings
		//- this prevents lifecycle surprises from procedural helpers that mix

		//  function foo() {if (cond) return m("div")}

//	Implementation Summary
//
//	1. Enforce API surface and semantic compatibility with 1.9.x branch
//	2. Improve the module's maintainability by reducing the storage
//		paths to a single mechanism.
//	3. Use the same single mechanism to support "private" and "user" data.
//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
//	5. Avoid exposing implementation details on user objects (eg. expando properties)
//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

Basic Usage:
============

$('#el').spin(); // Creates a default Spinner using the text color of #el.
$('#el').spin({ ... }); // Creates a Spinner using the provided options.

$('#el').spin(false); // Stops and removes the spinner.

Using Presets:
==============

$('#el').spin('small'); // Creates a 'small' Spinner using the text color of #el.
$('#el').spin('large', '#fff'); // Creates a 'large' white Spinner.

Adding a custom preset:
=======================

$.fn.spin.presets.flower = {

  length: 10,
  width: 20,
  radius: 0
}

$('#el').spin('flower', 'red');
