 * Implements language selection for multilingual elements
 * 
 * In certain environments, it's not feasible to neatly box away each
 * different language into its own section of the site. By marking elements
 * multilingual, you can emulate this behavior by only displaying only the 
 * message in the user's language. This reduced the "Tower of Babel" effect.
