slang::iterator_facade class

Base class that hides most of the iterator boilerplate from you. Derive from this template and then implement methods as follows:

Forward Iterators: (All of the following methods)

• DerivedT &operator=(const DerivedT& R);
• bool operator==(const DerivedT& R) const;
• const T& operator*() const;
• T& operator*();
• DerivedT& operator++();

Bidirectional Iterators: (All methods of forward iterators, plus the following)

• DerivedT& operator--();

Random-access Iterators: (All methods of bidirectional iterators excluding the following)

• DerivedT& operator++();
• DerivedT& operator--(); (and plus the following)
• bool operator<(const DerivedT& RHS) const;
• difference_type operator-(const DerivedT& R) const;
• DerivedT& operator+=(difference_type N);
• DerivedT& operator-=(difference_type N);
