Detailed Description

template<typename Container>
class kblib::counting_back_insert_iterator< Container >

Like a std::back_insert_iterator, but it keeps track of how many insertions it has made, allowing an end iterator to be created.

Attention: This iterator must be incremented and dereferenced exactly once for each assignment, in order to maintain the accuracy of the counter.
