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');
