I have a bunch of time windows and I want to transform them. For example, let's say I have a List of Pair<Int,Int> with values [8->12, 12->18, 18->22, 22->8]
How can I transform this to [0->8, 8->12, 12->18, 18->22, 22->24]? Is there a way to "map" a collection of T to another collection of T by eventually producing multiple `T`s from one?
