Wrong output given in api documentation of runningFold

[kfh]

There is a minor documentation error in the api docs of runningFold. The output in the example should be a list of lists:

will produce [], [1], [1, 2], [1, 2, 3] --> will produce [[], [1], [1, 2], [1, 2, 3]]

An example enumerates all list elements, not the list toString() result, but it indeed can be source of confusion
