Added line to load ESA tos and sic into IC3.conf. No testing needed

Added all options to UltimateBrier() and added BrierScore() from Luis Rodrigues. Still need to optimize UltimateBrier(). Besides, Veronica should review it.

Added BrierScore option. Now the two case types are programmed. Needs to be otimized and copied in all possible options, and needs to be reviewed by Veronica.

Allows to draw a rectangle over a portion of the map drawn by PlotEquiMap

Thx,
