Chai Things

Chai Things (v0.2.0, unmaintained since 2015) extends Chai assertion library with array element matchers like `include.something.that`, `all`, and `none`. Allows deep equality, property, and nested assertions on arrays. Last updated on npm in 2016; no releases for 9+ years. Use with Chai v4.x but may have compatibility issues. Alternative: use native Chai `members` matcher with deep equality or Lodash`_.some`/_.every.
