// InterceptGomegaFailures runs a given callback and returns an array of
// failure messages generated by any Gomega assertions within the callback.
//
// This is accomplished by temporarily replacing the *global* fail handler
// with a fail handler that simply annotates failures.  The original fail handler
// is reset when InterceptGomegaFailures returns.
//
// This is most useful when testing custom matchers, but can also be used to check
// on a value using a Gomega assertion without causing a test failure.
