YUI FocusManager Node Plugin Tests

# YUI Focus Manager Node Plugin Tests

## Test 1

Test the Focus Manager's ability to make a set of non-natively focusable elements focusable. Using the Focus Manager Node Plugin the user should be able to move focus among each `<li>` and be able to click each `<li>` by pressing the enter key while focused on it. (Note: This test won't work in Safari 3 as it doesn't support the `tabIndex` attribute on all elements.)
