-==Improvement needs==
-This code calculates VOI for all these situations: decision is an index; decision is an uncertain discrete variable; decision is an uncertain continuous variable.
-* calculate a:= unique from the decision parameter
-* if size(a)> samplesize^(1/3) then classify decision into bins 1..n, where n=ceil(samplesize^(1/3))
-* make an index i out of a or the bins, or deci:indextype if defined
-* replace the decision with whatif(decision is exploded by i)
-* calculate VOI as before.
