Notes
----
This uses the ["Flanagan / Miller device"](http://groups.google.com/group/nodejs/msg/0670a986a2906aeb) rather than the Crockford's original.
`typeOf` is taken from `jQuery.type`, which is more accurate than Crockford's original and even simpler
than the ["Flanagan / Miller device"](http://groups.google.com/group/nodejs/msg/0670a986a2906aeb).
There is [a more specific typeof()](http://rolandog.com/archives/2007/01/18/typeof-a-more-specific-typeof/) implementation worthy of consideration.
