Ability to add in global Vuex store to Vue Config

As described here https://vuex.vuejs.org/guide/state.html, Vuex provides a mechanism to "inject" the store (a global single source of truth, closely interacting with Vue) into all child components from the root component.

So I gonna close the issue. Keep up your work!
