LinearCombination.java evaluate method

[alexpArtos]

Hi all,

I think there is a problem with the evaluate() method in relations.objects.LinearCombination.
This line seems fishy if the condition is true:

final FieldT value = index == 0 ? one : input.get((int) index).mul(terms.get(i).value());

If index == 0, we want to add the constant value of the linear combination, which should be
terms.get(i).value(), not one.
