This example demos bi-directional hosts each with their own remote Button components.
app1exposes a red<button>App 1 Button</button>component.app2exposes a blue<button>App 2 Button</button>component.
Run yarn start. This will build and serve both app1 and app2 on ports 3001 and 3002 respectively.
Notice that app1 will asynchronously load app2's button and vice versa.
