> Key: MATH-379

>
> Utility that converts from indices in a multidimensional structure to the
> corresponding index in a one-dimensional array.
> E.g. assuming that the ranges (in 3D) of indices are {2, 4, 3}, we'll have
> that
> (0, 0, 0) corresponds to 0
> (0, 0, 1) corresponds to 1
> ...
> (1, 0, 0) corresponds to 12
> ...
> (1, 3, 2) corresponds to 23
> I propose to add this class in the "util" package.
