specifying -sequence fold.

Performs a side effecting function on each element of the specifying sequence in order.

Index with foreach on the data elements. Performs a side effecting function on the index and each element of the data sequence. It takes a function as a parameter. The function may return Unit. If it does return a non Unit value it is discarded. The [U] type parameter is there just to avoid warnings about discarded values and can be ignored by method users. The method has 2 versions / name overloads. The default start for the index is 0 if just the function parameter is passed. The second version name overload takes an Int for the first parameter list, to set the start value of the index. Note the function signature follows the foreach based convention of putting the collection element 2nd or last as seen for example in fold methods' (accumulator, element) => B signature.
