 *
 * - It must not have any dependencies
 *
 * - It must conceivably have a use in a wide variety of projects, not just
 *   Pokémon (if it's Pokémon-specific, Dex is probably a good place for it)
 *
 * - A lot of Chat functions are kind of iffy, but I'm going to say for now
 *   that if it's English-specific, it should be left out of here.
