Introduce tropism measure in king danger This patch adds the tropism measure as a new term in the king danger variable. Since we then trasform this variable as a Score via a quadratic formula, the main effect of the patch is the positive correlation of the tropism measure with some checks and pins information already present in the king danger code.
