Flip-flopping paths with items in a list

A general post for people that do not know Grasshopper that well: this is a simple example of re-ordering lists by paths. By using a series of a series you can create an index list that steps by the number of paths that steps by the number of items in each path. Confusing in the description, but it is easier to understand in the image. This example, of course, works for only paths that have the same number of items!
