docs: Convert a DynamoDB record into a JavaScript object.
  
  @param data [any] The DynamoDB record
  @param options [map]
  @option options convertEmptyValues [Boolean] Whether to automatically
  convert empty strings, blobs,
  and sets to `null`
  @option options wrapNumbers [Boolean]  Whether to return numbers as a
  NumberValue object instead of
  converting them to native JavaScript
  numbers. This allows for the safe
  round-trip transport of numbers of
  arbitrary size.
  
  @return [map] An object whose properties have been converted from
  DynamoDB's AttributeValue format into their corresponding native
  JavaScript types.
  
  @example Convert a record received from a DynamoDB stream
  var unmarshalled = AWS.DynamoDB.Converter.unmarshall({
  string: {S: 'foo'},
  list: {L: [{S: 'fizz'}, {S: 'buzz'}, {S: 'pop'}]},
  map: {
  M: {
  nestedMap: {
  M: {
  key: {S: 'value'}
  }
  }
  }
  },
  number: {N: '123'},
  nullValue: {NULL: true},
  boolValue: {BOOL: true}
  });
