Wrote SimpleErrorMatrix.
New implementation of ErrorKernel that considers order=1 and multiples
of the correct order. Still wrong: the dominant eigenvector has negative
entries.
Replaced JAMA with Apache Commons math for matrices. Wrote a stationary
distribution calculation method that actually works. Other small
changes. The current result is π=[0.21682, 0.21876, 0.06023, 0.22072, 0,
0.06077, 0, 0.2227].
Write vector instead of matrix.
Cleaned up, added max iterations for stationary distribution, and
reverted printing of vector instead of matrix.
