## <paper-checkbox>
`paper-checkbox` is a button that can be either checked or unchecked. User can
tap the checkbox to check or uncheck it. Usually you use checkboxes to allow
user to select multiple options from a set. If you have a single ON/OFF option,
avoid using a single checkbox and use `paper-toggle-button` instead.
