Correlations

[WillPugs]

Correlations between spins in the 1D H=/=0 case are not what we would expect, there is too little correlation.

[WillPugs]

After implementing the newer algorithm we still have the same issue except that there is now a little more correlation at certain random temperatures.

Maybe we should put an upper limit on the range of correlations because after the halfway point from r=0 to r=length of strip we are calculating the correlation function at a value that we have already calculated due to the periodic nature of the boundary conditions.

[WillPugs]

After implementing non-sequential iteration the simulated correlations more closely match the expectation values. However, the issue with the range of correlations still persists.

Fixed the issue pertaining to the range of correlations.
