A function that returns a vuex module object with seamless 2-way sync for firestore.

@param {IEasyFirestoreModule} userConfig Takes a config object per module
@param {*} FirebaseDependency The Firebase dependency (non-instanciated), defaults to the Firebase peer dependency if left blank.
@returns {IStore} the module ready to be included in your vuex store
