Detailed Description

template<typename BUF, typename T>
class cb_iterator< BUF, T >

This code is heavily based on boost circular_buffer: http://www.boost.org/doc/libs/1_55_0/doc/html/circular_buffer.html The interface of this version and the original boost version is (as much as possible identical).

I did leave out some of the more fancy methods like insert/remove in the middle of the buffer or linearize the buffer. If we ever need those we can add them of course. So (for now) this class represents a dynamically sized circular buffer with (efficient) {push,pop}_{front,back} and operator[] methods. It also offers random access iterators. For much more details check the boost documentation. Random access iterator for circular_buffer.
