NAME
       std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference > -
       Common iterator class.


SYNOPSIS
       #include <iterator>

   Public Types
       typedef _Distance difference_type
           Distance between iterators is represented as this type.
       typedef _Category iterator_category
           One of the tag types.
       typedef _Pointer pointer
           This type represents a pointer-to-value_type.
       typedef _Reference reference
           This type represents a reference-to-value_type.
       typedef _Tp value_type
           The type 'pointed to' by the iterator.

Detailed Description
   template<typename _Category, typename _Tp, typename _Distance = ptrdiff_t,
       typename _Pointer = _Tp*, typename _Reference = _Tp&>
       struct std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference
       >"Common iterator class.

       This class does nothing but define nested typedefs. Iterator classes
       can inherit from this class to save some work. The typedefs are then
       used in specializations and overloading.

       In particular, there are no default implementations of requirements
       such as operator++ and the like. (How could there be?)

       typedef _Tp std::iterator< _Category, _Tp, _Distance, _Pointer,
       _Reference >::value_type
       The type 'pointed to' by the iterator.
