Detailed Description

This file implements iterator facade classes for writing stl conformant iterators.

With using these facades writing iterators for arbitrary containers becomes much less cumbersome as only few functions have to be implemented. All other functions needed by the stl are provided by the facades using the Barton-Nackman trick (also known as curiously recurring template pattern.
