/**
 * Global Reset of all HTML Elements
 *
 * Resetting all of our HTML Elements ensures a smoother
 * visual transition between browsers. If you don't believe me,
 * try temporarily commenting out this block of code, then go
 * and look at Mozilla versus Safari, both good browsers with
 * a good implementation of CSS. The thing is, all browser CSS
 * defaults are different and at the end of the day if visual
 * consistency is what we're shooting for, then we need to
 * make sure we're resetting all spacing elements.
