  `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.
  
  Example:
  
      <paper-checkbox>label</paper-checkbox>
  
      <paper-checkbox checked> label</paper-checkbox>
  
  ### Styling
  
  The following custom properties and mixins are available for styling:
  
  Custom property | Description | Default
  ----------------|-------------|----------
  `--paper-checkbox-unchecked-background-color` | Checkbox background color when the input is not checked | `transparent`
  `--paper-checkbox-unchecked-color` | Checkbox border color when the input is not checked | `--primary-text-color`
  `--paper-checkbox-unchecked-ink-color` | Selected/focus ripple color when the input is not checked | `--primary-text-color`
  `--paper-checkbox-checked-color` | Checkbox color when the input is checked | `--default-primary-color`
  `--paper-checkbox-checked-ink-color` | Selected/focus ripple color when the input is checked | `--default-primary-color`
  `--paper-checkbox-checkmark-color` | Checkmark color | `white`
