Perform post-processing of the result tables from operators CALC_G and POST_K1_K2_K3.

The various possible operations are:


* normalization of the curvilinear abscissa,


* calculation of the angle of bifurcation,


* counting fatigue cycles,


* calculation of the fatigue crack advance increment,


* accumulation of fatigue cycles,


* propagation management,


* calculation of the equivalent stress intensity factor,


* calculation of :math:`{(\Delta K)}_{\mathit{eq}}` used for propagation in variable amplitude,


* setting the negative values of the stress intensity factors :math:`{K}_{1}` to zero and calculating the new return rates :math:`G` and/or :math:`{G}_{\mathit{IRWIN}}` by the Irwin formula.

Produces a table data structure.
