This release adds diagnostic test failures if verifiers clash.

• Fail test if code creates multiple instances of any single verifier. This inadvertently undid its
  swizzling, leading to test failures that were tricky to diagnose. Now a failure message provides
  guidance.
• Also fail if an AlertVerifier and a PresentationVerifier exist simultaneously, since they both
  swizzle UIAlertViewController. This has the potential to change test results, so this is marked as
  a major release.

Version 4.2.0

Added DismissalVerifier to capture calls to dismiss view controller. The Swift version has a
verify method which checks:

• That the dismissed count is 1.
• The animated flag.
• The dismissed view controller, if provided.

Like the other verifiers, it also has a capturedCompletion to capture any production code
completion handler, and a testCompletion so that test code can supply its own completion handler.
