Message Formatting

MessageFormat, ChoiceFormat

• Put together sequences of strings, numbers,
  dates, and other formats to create messages.

• Facilitate localization because they:
  -- prevent hard-coding of message strings
  -- prevent hard-coding of the concatenation

• Enables localizers to change the content, format,
  and order of any text as appropriate for any language.

• Choice formats let localizers create more natural messages,
  avoiding phrases like "3 file(s)".
