title: Use Vue.js plugin in Vuex Store module
body: <p>I am trying to use a Vue.js plugin inside of a Vuex Store module.</p>
  
  <p>In a <em>component</em>, I am able to call it like this: <code>this.$plugin()</code>. However, in a <em>module</em>, <code>this</code> is not set. I thought <code>Vue.$plugin()</code> would work since I initialize the plugin with <code>Vue.use(plugin)</code> and <em>Vue</em> being a global variable, but it doesn't.</p>
  
  <p>How do I reference the plugin from a module?</p>
