// RegisterTestSuite tells ogletest about a test suite containing tests that it
// should run. Any exported method on the type pointed to by the supplied

// zero value of the test suite type.

//
//     // Some value that is needed by the tests but is expensive to compute.
//     var someExpensiveThing uint
//
//     type FooTest struct {
//       // Path to a temporary file used by the tests. Each test gets a
//       // different temporary file.
