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')
