Alien sightings: tab layout

As-is, the app is sort of busy with the graph on top of the table. Given that this is a dashboard, it might be nice to instead separate the two outputs.

The last step in building your dashboard is to take the plotOutput() and tableOutput() you've built and add the tab layout.

Add the tab panel layout and the two tabs. The first one should contain the plot, and the second one should contain the table. Feel free to name them whatever makes sense to you!
