/**
 * UIView (CompactConstraint), a class category from Marco Arment’s
 * [CompactConstraint](https://github.com/marcoarment/CompactConstraint)
 * library, is integrated with Cephei. CompactConstraint provides an Auto Layout
 * grammar and methods that are easier to use and understand than UIKit’s built
 * in functions for programmatically adding constraints.
 *
 * Refer to
 * [its readme](https://github.com/marcoarment/CompactConstraint/blob/master/README.md)
 * to learn how to use it. There are two changes to note: most importantly, the
 * methods have an `hb_` prefix, and two methods that are marked as deprecated
 * in the original project have been removed.
 *
 * CompactConstraint is licensed under the MIT License.
