//SynchronizedBeforeSuite blocks are primarily meant to solve the problem of setting up singleton external resources shared across
//nodes when running tests in parallel.  For example, say you have a shared database that you can only start one instance of that
//must be used in your tests.  When running in parallel, only one node should set up the database and all other nodes should wait
//until that node is done before running.
//
//SynchronizedBeforeSuite accomplishes this by taking *two* function arguments.  The first is only run on parallel node #1.  The second is
//run on all nodes, but *only* after the first function completes successfully.  Ginkgo also makes it possible to send data from the first function (on Node 1)
//to the second function (on all the other nodes).
//
//The functions have the following signatures.  The first function (which only runs on node 1) has the signature:
//
//	func() []byte
//
//or, to run asynchronously:
//
//	func(done Done) []byte
//
//The byte array returned by the first function is then passed to the second function, which has the signature:
//
//	func(data []byte)
//
//or, to run asynchronously:
//
//	func(data []byte, done Done)
//
//Here's a simple pseudo-code example that starts a shared database on Node 1 and shares the database's address with the other nodes:
//
//	var dbClient db.Client
//	var dbRunner db.Runner
//
//	var _ = SynchronizedBeforeSuite(func() []byte {
//		dbRunner = db.NewRunner()
//		err := dbRunner.Start()
//		Ω(err).ShouldNot(HaveOccurred())
//		return []byte(dbRunner.URL)
//	}, func(data []byte) {
//		dbClient = db.NewClient()
//		err := dbClient.Connect(string(data))
//		Ω(err).ShouldNot(HaveOccurred())
//	})

//and *only* after all other nodes have finished and exited.  This ensures that node 1, and any resources it is running, remain alive until
//all other nodes are finished.
//
//Both functions have the same signature: either func() or func(done Done) to run asynchronously.
//
//Here's a pseudo-code example that complements that given in SynchronizedBeforeSuite.  Here, SynchronizedAfterSuite is used to tear down the shared database
