⚠️ Breaking Changes Ahead ⚠️

For SwiftCheck's 5th birthday, we sped up all the insides and moved the furniture around a bit.

• The insides of Gen move an order of magnitude quicker because of framework-wide simplifications.
• We now match Swift's naming convention for some big combinators (esp. map and flatMap). Update your code accordingly!
• Currying syntax has been removed framework-wide and labels have been made more semantically meaningful.
• Gen.fromShufflingElementsOf is unbelievably fast now.
• pseudo-Equatable instances for modifier types have been removed.
• More things have been documented and what documentation there is has been improved.
• Quantifiers and property binders have more informative @warn_unused_result messages.

Finally, for the pièce de résistance, cover has been made a first-class citizen of the framework. For those times when a particular property of a spec should hold a certain percentage of the time, you can ask SwiftCheck how well it's been covered. If we don't rise to meet your set goals, the test fails!
