                                                  EachPage iterates over each page of a paginated request object. The fn parameter should be a function with the following sample signature:

                                                  func(page *T, lastPage bool) bool {
                                                      return true // return false to stop iterating

                                                  Where "T" is the structure type matching the output structure of the given operation. For example, a request object generated by DynamoDB.ListTablesRequest() would expect to see dynamodb.ListTablesOutput as the structure "T". The lastPage value represents whether the page is the last page of data or not. The return value of this function should return true to keep iterating or false to stop.
