[eigen] eigen2 co-existing with eigen3

[Radu Bogdan Rusu <rusu@xxxxxxxxxxxxxxxx>]

Since it seems that eigen2 uses the same namespace as eigen3, is there a preferred behavior on them co-existing happily? 
We have some bits of code that are now using both (well, importing the headers at least - through the use of different 
packages), and the only solution that we found was to patch beta1 to rename the namespace from Eigen to Eigen3.

Is that the preferred behavior at this point?

Thanks,
Radu.
