Use this to combine two groups into one, with duplicates automatically removed — for example, merging the usage types from two scenarios into a single master list.
Set vs. List: a List (array) keeps items in order and can hold duplicates — you access items by position, like "the 3rd item." A Set has no order and no duplicates — adding an item that's already there does nothing, and there's no "position" to ask for. Sets are for asking "is this here?" and for comparing groups of things; Lists are for ordered, step-by-step sequences.
