Hi all:

I am a new guy about EIGEN license declaration.
If I use EIGEN 3.2.8, and only use Eigen/Core, Eigen/Geometry,
no any modification about EIGEN, and not enable EIGEN_MPL2_ONLY flag in my code,
What is the license about EIGEN?
Should I open source if not enable EIGEN_MPL2_ONLY build?

Thanks!

Duncan
