Refs #10432. Cleaning up PoldiAutoCorrelationCore, adding norm counts
Refs #10432. Added algorithm
Refs #10432. Adding latest parameters for comparison.

Current software works with those parameters, so for comparison they are required.
Refs #10432. First steps of algorithm.
Refs #10432. Small changes to PoldiCalculateSpectrum2D
Refs #10432. Removing magic number from CostFuncLeastSquares
Refs #10432. Some more refactoring in PoldiAutoCorrelationCore

This is needed as preparation for implementing the residual calculation, because some of the steps are actually different.
Refs #10432. Added PoldiResidualCorrelatonCore.

Algorithm is working correctly.
Refs #10432. Refactored PoldiResidualCorrelationCore, added tests
