willContinueTo Expectation stubbed

This matcher will address the problems with willNot.finish() and others under asynchronousTests, by waiting for truth condition when the test expires. Currently implemented with a trampoline and swizzling. When this is finished it can be modified for the Expecta project, if it is relevant to them.
Test the original implementation works
applyMatcher:to: for willContinueTo

Crashing on trampoline invoking original implementation
Original method implementation function signature is now typed
Negation for willContinueTo.

The usage of double negatives in the Unit Tests wouldn't make sense in production code, but it keeps the tests in a common format, and the failure messages the same.
