100Interface that acts as an iterator for deserializing maps.
101 The deserializer returns an instance that the record uses to
102 read vectors and maps. An example of usage is as follows:
103
104 <code>
105 Index idx = startVector(...);
106 while (!idx.done()) {
107   .... // read element of a vector
108   idx.incr();
