Demonstrate some uses of the --target lib functionality of Vue CLI 3.
There are two entry files which are interesting: src/library-entry.js and src/library-plugin.js.
library-entry just imports two components and exports them as an object, so you can use them as demonstrated in the library-demo.html.
library-plugin actually builds a tiny Vue plugin, so you can use them with Vue.use() as demonstrated in the plugin-demo.html
npm install
npm run build-lib
