// RegisterTestSuite tells ogletest about a test suite containing tests that it
// should run. Any exported method on the type pointed to by the supplied
// prototype value will be treated as test methods, with the exception of the
// methods defined by the following interfaces, which when present are treated
// as described in the documentation for those interfaces:
//
//  *  SetUpTestSuiteInterface
//  *  SetUpInterface
//  *  TearDownInterface
//  *  TearDownTestSuiteInterface
//
// Each test method is invoked on a different receiver, which is initially a
// zero value of the test suite type.
//
// Example:
//
//     // 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.
//       tempFile string
//     }
//     func init() { ogletest.RegisterTestSuite(&FooTest{}) }
//
//     func (t *FooTest) SetUpTestSuite() {
//       someExpensiveThing = ComputeSomeExpensiveThing()
