- * A BasicHashtable stores entries that are indexed by hash code in place

- * higher level of abstraction.
- *
- * TKey: The key type.
- * TEntry: The entry type which is what is actually stored in the array.

- *     bool operator==(const TKey& other) const;  // return true if equal
- *     bool operator!=(const TKey& other) const;  // return true if unequal
- *
- * TEntry must support the following contract:

- *
- * This class supports storing entries with duplicate keys.  Of course, it can't
- * tell them apart during removal so only the first entry will be removed.
- * We do this because it means that operations like add() can't fail.
