Refactor

As all points from the epic refactor issue are closed #47 (closed) I am merging this in to master in order to unblock development.

frontend/src/components/HelloWorld.vue

-<template>
-  <div>
-    <span>{{msg}}</span>
-    <span>{{token}}</span>
-  </div>
-</template>
-
-<script>
-  import axios from 'axios'
-
-  export default {
-    name: 'HelloWorld',
-    data () {
-      return {
-        msg: 'Welcome to Your Vue.js App',
-        token: ''
-      }
-    },
-    created: function () {
-      axios.post('http://localhost:8000/api-token-auth/', {
-        username: 'robin',
-        password: 'p'
-      }).then(token => {
-        this.token = token.data.token
-      })
-    }
-  }
-</script>
