title: Disabling a checkbox by checking another checkbox in vuetify
body: <p>So I have several <code>checkboxes</code> and two of them should function like <code>radiobuttons</code> meaning that if I click on one, the other one should become disabled and vice versa (I know I can do it using <code>radiobuttons</code> but I need to use <code>checkboxes</code>). What's the best way to do it?</p>
  
  <p>Here is my code for those two <code>checkboxes</code>:</p>
  
  <pre><code>&lt;v-checkbox label="Check1" value="Check1" v-model="Check1" &gt;&lt;/v-checkbox&gt;
  
  &lt;v-checkbox label="Check2" value="Check2" v-model="Check2" &gt;&lt;/v-checkbox&gt;
  </code></pre>
