/*
 * HomePage
 *
 * This is the first thing users see of our App, at the '/' route
 *
 * NOTE: while this component should technically be a stateless functional
 * component (SFC), hot reloading does not currently support SFCs. If hot
 * reloading is not a neccessity for you then you can refactor it and remove
 * the linting exception.
