Other information

To do:

• [x] Loading state
• [x] Disabled state (ability to disable a switch, or set disabled when toggle is also loading)
• [x] Show error message if switch fails to toggle
• [x] A label position property that changes the orientation of the label from being displayed left or right of the toggle UI
• [x] ARIA considerations (https://www.w3.org/WAI/ARIA/apg/patterns/switch/)
• [x] Keyboard interactions

To-do ARIA considerations (https://www.w3.org/WAI/ARIA/apg/patterns/switch/):

• [x] A visible label referenced by the value of aria-labelledby set on the element with role switch.
• [x] aria-label set on the element with role switch.
• [x] When on, the switch element has state aria-checked set to true.
• [x] When off, the switch element has state aria-checked set to false.

@gracetxgao I went ahead and made updates to the aria labels. Lmk if you have any questions.

In the basic switch example, clicking on the disabled or loading switches toggles the default switch. Clicking on the switch in switch-label-positions-example also toggles the default switch. I think you may need to add form controls to examples.
