[Anton Gladky <gladky.anton@xxxxxxxxx>]

I added the Eigen development trunk directly. They move to Eigen3, what is
planned to be for may.

I think it is better for us now to adopt the wrapper to Development branch,
it will be much more easier later to switch to "packaged eigen3".

What do you think?
