Alien sightings: add inputs

The National UFO Reporting Center (NUFORC) has collected sightings data throughout the last century. This app is going to allow users to select a U.S. state and a time period in which the sightings occurred.

Remember that when they're added, the inputs should look as they do here, though they won't yet be in the sidebar:

The usa_ufo_sightings dataset, plus the shiny, ggplot2, and dplyr packages have all been loaded for you.
