Thanks for the typescript support! Any chance options argument of install method can be extracted into its own interface for proper type-checking in Vue.install call?

import VueAnalitycs, { InstallOptions } from "vue-analytics";

// type-checking here
const options: InstallOptions = { 
  id: "xxx",
  router,
};

Vue.use(VueAnalytics, options);

@romansp to be honest, I'm glad that a PR for it has been open because I'm not really a typescript guy so I don't know too much.
if you want to support it, be my guest and open a PR too.

Open source is nice especially for this :)
