Hello Pshemek, I don't really know what a 2D multi-index container is
supposed to be or how can one devise a multi-index structure comparable
with
a vector<vector<T> >.
Aren't you by chance referring to Boost.MultiArray?

http://boost.org/libs/multi_array/doc/index.html

This lib does indeed provide data structures resembling vector of
vectors
in a number of ways, while being more efficient and providing nicer
syntax
and extended functionality.
