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

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?)
