Fixed erroneous indentation in relaxOver.
Wrote and tested new algorithm for increasing the bandwidth.
Deleted redundant # from a comment.
Added new convergence policy that examines differences in the expectation.
Deleted redundant trailing 0 in a decimal.
Added pre-optimization hook, and now both hooks run on first optimization.
Added XY test.
Now the normalization method takes the product UV instead of just U.
Removed the absorbed matrix transpose in the 1D contraction algorithm.
Tweaked 1D ferromagnet test by adding a minus sign and tweaking the convergences
Added "Absolute" to computeAbsoluteLimitingLinearCoefficient.

This was done to emphasize that the result is the
absolute value of the limiting linear coefficient
rather than the actual value.
Cosmetic:  Fixed typo in fold comment.
Wrote function absorbCenterSSIntoLeftEnvironment.

This is the opposite direction analog of
absorbCenterSSIntoRightEnvironment.
Now the Haldane-Shastry approximation uses 10000 terms.
Now the Haldane-Shastry test has ferromagnetic terms.
Made some tweaks to the 1D Haldane-Shastry test.
Added XYZ test.
Tweaked several of the 1D simulator tests.
Now the ferromagnetic coupling test uses the estimated one side expectation.
Moved the estimated one site expectation functionality into 1D system.
