# I originally needed to create a sidebar partial that had a div area where I could place custom links into. Finally found it.
# When I was trying to figure this out before and realized I needed to pass the view into :layout, rather than just using render 'layout'. Not sure why the block can't be passed otherwise but nonetheless...

You can now create a spinner using any of the variants below:

$("#el").spin(); // Produces default Spinner using the text color of #el.
$("#el").spin("small"); // Produces a 'small' Spinner using the text color of #el.
$("#el").spin("large", "white"); // Produces a 'large' Spinner in white (or any valid CSS color).
$("#el").spin({ ... }); // Produces a Spinner using your custom settings.

$("#el").spin(false); // Kills the spinner.

sum(20, 100000) // => RangeError: Maximum call stack size exceeded
