   7       *
   8       * Validator class that allows to make chained validators so that we can validate for more complex
   9       * rules. The parameter for the constructor is an array of Validator objects that we are going to
  10       * chain.
  11       *
  12       * Internally, this class is not actually going to chain the validators but their rules, one after each
  13       * other using the Validator::addValidator() method.
  14       *
  15       * You can either create your own brand new custom Validator class and add the rules that you need
  16       * or if you know that some Validator classes are already doing what you need, you can always 
  17       * chain them by using the ChainedValidator class.
  18       *
  19       * Example:
  20       *
  21       * <pre>
  22       *  $val = new ChainedValidator( Array( new StringValidator(),
  23       *                                      new UsernameValidator());
  24       *  $result = $val->validate( $value );
  25       * </pre>
