virtual void	insertEntry (const KeyType &key, PWCEntry *entry)
	Indicate that an entry has just been inserted.
std::vector< PWCEntry * >	getPossibleEntries (const KeyType &key) const
	Find the set of entries that could be replaced given that we want to add a new entry with the provided key.
iterator	begin ()
	Returns an iterator to the first entry of the dictionary.
const_iterator	begin () const
	Returns an iterator to the first entry of the dictionary.
iterator	end ()
