  2016. Designed to load GMR 4-phase data which use the following convention for phase cycles
  2017. P1 P2

  2019. Stack 2 -> 0 pi/2 | <-- <--
  2020. Stack 3 -> pi/2 0 <-- | <--
  2021. Stack 4 -> pi/2 pi/2 <-- <--
  2022. The cycle is determined by stack indice. Walbrecker proposes for pulse2 data (Stack2 - Stack1) / 2
  2023. equivalently (Stack 4 - Stack3) will yield the same voltage response wrt. the second pulse.
  2024. Alternatively Stack 4 can be converted to be aligned with Stack 1 by negating, and Stack 3 Can be aligned with Stack 2 by negating
  2025. Then there are just the two phase cycles that can be stacked like normal.
  2026. Unfortunately, we need to stack each cycle first, then perform corrections for phase cycling. The reason for this is that otherwise,
  2027. the entire point is lost, as the signal that is desired to be cancelled out may not be balanced evenly across the stacks. That is to say,
  2028. if there is an uneven number of a certain phase cycle.
  2029. We could, I suppose impose this condition, but I think I would rather not?
  2030. + more samples for std. deviation calculation
  2031. + single spikes will have less residual effect
  2032. - can no longer do normality tests etc. and remove data that are suspect.
  2033. - requires a dumb stack, and may also require removal of entire stacks of data
  2034. Additonally, the GMR varies phase as a function of pulse moment index, so that the first pusle moment is zero phase, the second is pi/2 the third is zero ...
  2035. This however, is altered by the above convention. It gets a little complicated...
