Spacing changes to eigenvalue lab.
Some more spacing fixes in the eigenvalues lab.
Modified first problem in eigenvalues lab.
Added reference to the eigenvalue lab refering to the QR decomposition of
an upper Hessenberg matrix.
Merge branch 'givens' into eig

Altered the solutions file for MarkovGraph to match the format that
was given to the students. Also fixed a couple of code errors.
Fixed another error in the solutions file.
Commented out the hessenberg problem in the QR algorithm lab.
This will be uncommented if we can get a better solver worked into this
lab.
