Delivering utilities ☂️

[davidmenendez]

Some components, patterns, and tooling has the potential to be (re)categorized as a "utility", which is something we really haven't thought about in the past.

Cascade is a great example of something that isn't necessarily a "component" but is a utility that can be used in any number of situations. There are probably numerous helpful utilities that we have in our codebase that we can extend to users. Another good example of a common utility function that we have and could export is the hook that is used in components like ActionBar TagOverflow and TagSet for determining overflow of a list of elements in a given area.

### Tasks
- [ ] identify hooks, components, or other code that could be extended as a utility to consumers
- [ ] identify best way to offer these utilities (new package?)

Work In Progress.
