title: How can I override the user-select: none in RadioButton and CheckBox control labels?
body: <p>Currently for pre 1.0.0 releases Material-UI does not allow text selection on RadioButton and Checkbox control labels.</p>

  <p>What I'm trying to achieve is being able to highlight the text in the option label as per this screenshot:</p>
