/**
 * VirtualizedScroller
 * A component for efficiently rendering large lists of variable height items.
 * VirtualScroller works by measuring each list item's height as it's being rendered, and then, as the user scrolls,
 * it hides the items that are no longer visible, and shows the now-visible items as they're scrolled to.
 * The hidden items at the top are compensated by setting padding-top on the list element, and the hidden items
 * at the bottom are compensated by setting padding-bottom on the list element.
 * The component listens to scroll / resize events and re-renders the currently visible items as the user
 * scrolls (or if the browser window is resized).
 * Set window['VirtualScrollerDebug'] = true; to output debug messages to console.
