eigen/doc/example.cpp
Benoit Jacob 86220784b6 part 2 of the reorganization. Benefits/changes:
1) Eigen2 co-installable with Eigen1 without conflict, without affecting programs including either.
2) #include<Eigen/Core> without the .h without conflict with the Core/ directory
3) Uniformize coding style of the CMakeLists.
