// IMPORTANT: Do NOT use ES2015 features in this file (except for modules).
// This module is a runtime utility for cleaner component module output and will
// be included in the final webpack user bundle.
// Forked directly from the vuetify-loader https://github.com/vuetifyjs/vuetify-loader/blob/master/lib/runtime/installComponents.js
