The task

I find myself fairly regularly calling ```python plt.contour(boolean_2d_array, levels=[.5], ...) ``` to draw the boundary line between True and False regions on a boolean 2d array. Without `levels=[.5]`, one gets the default 8 levels which go at 0, 0.15, 0.3, 0.45, 0.6, 0.75, 0.9, 1.05 resulting in all the contour…
