/**
 * An extension of {@code StringMap} that imposes a total ordering on its keys.
 * The map is ordered according to the natural ordering of its keys. This order is reflected when
 * {@link #forEach(BiConsumer) consuming} the key-value pairs with a {@link BiConsumer} or a {@link TriConsumer}.
 * <p>
 * This interface views all key-value pairs as a sequence ordered by key, and allows
 * keys and values to be accessed by their index in the sequence.
