-
-$('#el').spin() // Creates a default Spinner using the text color of #el.
-$('#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.

-, width:  20
-, radius:  0
