Feature-level testing in Swift without UI Testing

This library is an experiment in UIKit feature-level testing, but without Apple UI Testing (XCUITest).

The goal is to get to ~80% feature-parity with UI Testing but be as reliable and fast as XCTest.

It is still a work-in-progress but supports a wide range of interactions with common UIKit controls. Pushing/popping, presenting/dismissing view controllers, buttons, table views, sliders, switches, and alerts are all supported.
