Public Attributes
double	H
	The target variable for absolute entropy, computed as: H(map)=Sumx,y{ -p(x,y)·ln(p(x,y)) -(1-p(x,y))·ln(1-p(x,y)) }
double	I

double	mean_I
	The target variable for mean information, defined as information per cell: mean_I(map) = I(map) / (cells)
double	effectiveMappedArea
	The target variable for the area of cells with information, i.e.
