-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 = {
-  lines:   9
-, length: 10
-, width:  20
-, radius:  0
-}
-
-$('#el').spin('flower', 'red')
