- iterators store pointers instead of references to the HashTbl.
This lets us use the default bitwise copy/assignment
- add empty constructor for iterators. It returns the equivalent to end().
This lets us do this:
HashTbl<label>::iterator iter;
// some time later
iter = find(Value);
- erase(const HashTbl<AnyType, Key, AnyHash>&) is now more generous.
Only the Key type matters, not the hashing function.
