eigen/tvmet-1.7.1/testsuite/TestVectorOperators.h
Benoit Jacob 3036eeca0a Starting Eigen 2 development. The current plan is to use the last 
release of tvmet (inactive for 2 years and developer unreachable) as the
basis for eigen2, because it provides seemingly good expression template
mechanisms, we want that, and it would take years to reinvent that
wheel. We'll see. So this commit imports the last tvmet release.
