The original version made heavy use of macros to sidestep some of the older

and the macro use was starting to become a maintenance burden it has been
rewritten to use templates instead of macros for the implementation classes.

The container objcet is now smaller thanks to using <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">compressed_pair</span></code>

of a member pointer.
