Add stdout debugging for normalization

[gadomski]

@alexsmartens can you pull down this branch, test (either with env CTEST_OUTPUT_ON_FAILURE=1 make test or test/normalization), and put the output in this pull request's discussion? Thanks.

There is the issue that I have:

I think I might have found the bug. It was a combination of two things I often screw up when working with Eigen (forgetting to replicate out vectors, and the fact that isApprox passes ok even if the matrix dimensions don't agree), and I'm glad your version of Eigen caught it.

If you can pull down this latest version of the branch and test, I would appreciate it.

Edit: To be clear, this bug is only in the test suite, not in the code itself, so this won't fix/change any of your original issues.

Thank you Pete!
