/**
 *
 *  Maps a value to a string that pluralizes the value properly.
 *
 *  ## Usage
 *
 *  expression | i18nPlural:mapping
 *
 *  where `expression` is a number and `mapping` is an object that indicates the proper text for
 *  when the `expression` evaluates to 0, 1, or some other number.  You can interpolate the actual
 *  value into the text using the `#` sign.
 *
 *  ## Example
 *
 *  ```
 *  <div>
 *    {{ messages.length | i18nPlural: messageMapping }}
 *  </div>
 *
 *  class MyApp {
 *    messages: any[];
 *    messageMapping: any = {
 *      '=0': 'No messages.',
 *      '=1': 'One message.',
 *      'other': '# messages.'
 *    }
 *    ...
 *  }
 *  ```
