The fact that one needs to do an explicit instantiation to get it working.
But I didn't know it was a requirement of the visualizing engine until I
read your explanation below. So I guess this is the best we can
do. Also, I see that the VISUALIZE_MULTI_INDEX_CONTAINER
macro is now cleaner, without the nasty ID parameter.

There's an obvious evolution path, namely supporting the rest of
node types. Random access should be straightforward, as elements
can easily be traversed in a linear fashion much as you're already doing with
sequenced nodes --so if you want some clues about that please tell me so.
As for the other node types (ordered and hashed) traversal is not that simple,
I guess it'd help a lot to see how the built-in visualizers for std::map and
stdext::hash_map are doing.
