+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');
