Dump more info on eigenvalues and fix bug in eigenvector printing
- dump more info on eigenvalues to log file
- add histogram for all eigenvalues to AlignUpdateTool
- fix bug in printing of eigenvector (it was printing a column rather than a row of U)
- update Tracker alignable
I rebased against the branch in !286 (merged), so perhaps best merge after that.
