Description
I have noticed that, while ScalaZ provides an implementation for Zippers, cats doesn't seem to have one yet. Would that be a useful addition to this project?, and if so, should we use the ScalaZ implementation as a reference?
According to the Haskell wiki, the concept was first formulated in a paper by Gerard Huet.

Research direction
The issue names no repository files, tests, or entry points. Start by reviewing ScalaZ's zipper implementation and the linked Haskell references, then inspect cats' existing module and API conventions. The issue does not define an agreed scope or completion criteria, so the desired API and tests would need to be established first.
