Add example demonstrating a simple data-fetching application

[sidiousvic]

We need to establish an in-component example to demonstrate how one could do data-fetching with phantom.

End result could be akin to this rough sketch (using GraphQL):

async function phantomComponent() {
  const usernameQuery = gql`{  data  {  username  } }`
  const username = await fetchUsername(query);
      return `${Profile(username)}`;
  }
}

How async functions behave with the phantom engine remains to be seen. 😈

Hello @sidiousvic 👋 Is it ok if I work on this issue? I have an idea! Would it be ok to add a fourth example that has some async fetch calls?

@mussinbenarbia Go ahead! Let me know if you run into a fundamental shortcoming of Phantom 👀
