title: what is vuex-router-sync for?
body: <p>As far as I know <code>vuex-router-sync</code> is just for synchronizing the <code>route</code> with the  <code>vuex store</code> and the developer can access the <code>route</code> as follows:</p>
  
  <pre><code>store.state.route.path
  store.state.route.params
  </code></pre>
  
  <p>However, I can also handle <code>route</code> by <code>this.$route</code> which is more concise.</p>
  
  <p>When do I need to use the route in the store, and what is the scenario in which I need vuex-router-sync?</p>
