NonlinearStatic::load_path gives the load factor against the step fraction, piecewise linear from [0, 0] to fraction 1, so a step can unload or reverse its loads and prescribed displacements (cyclic loading of path-dependent materials). Validated (2 to 1000 finite points, increasing fractions), with load_factor and next_turn for the solver's increments.
