This adds event types to logit path following:

  • LogitBifurcationEvent, providing a bracketing of a bifurcation point when detected
  • LogitPerturbationEvent, which signals when a perturbation is activated/deactivated to resolve the bifurcation and continue tracing.

These are now reported in the command-line tool when the -b flag is provided.

A list of bifurcation brackets is returned in the LogitResult class in pygambit.

Closes #186
