Currently, to import a component to a page, I appear to have to import `Vue` itself, then the component (with `Vue.component`). Where do I globally register components and why do I need to import `Vue` itself? Apologies if these are silly questions. <!--cmty--><!--cmty_prevent_hook--> <div align="right"><sub><em>This question is available on <a href="https://nuxtjs.cmty.io">Nuxt.js</a> community (<a href="https://nuxtjs.cmty.io/nuxt/nuxt.js/issues/c40">#c40</a>)</em></sub></div>
