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
 The target variable for absolute "information", defining I(x) = 1 - H(x)
double mean_H
 The target variable for mean entropy, defined as entropy per cell: mean_H(map) = H(map) / (cells)
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.
unsigned long effectiveMappedCells
 The mapped area in cells.
