mode check
I would like to allow the check plots routine to plot asymmetric plots around the mean. This would fix a couple of issues:
- when the posterior mode goes near or at the boundary, currently the plots display the objective function for very narrow or null intervals;
- using very large (or inf) values for mode_check_neighborhood_size, would allow to plot the objective function for the entire domain, which may possibly allow to visualize alternative local optima faraway from the current one;
