SSE Streaming Example

To use SSE streaming (only included with paid IEX subscription plans)

// both `IEXCloudClient` and `SSEClient` are `IDisposable`,
// so they should both be wrapped in `using()` statements
using (var iexCloudClient = 
	new IEXCloudClient("publishableToken", "secretToken", signRequest: false, useSandBox: false))
using (var sseClient = iexCloudClient.StockPrices.SubscribeStockQuotesUS(symbols: new string[] { "spy", "aapl" }, 
	UTP: false, interval: StockQuoteSSEInterval.OneSecond))
{
	sseClient.Error += (s, e) =>
	{
		Console.WriteLine("Error Occurred. Details: {0}", e.Exception.Message);
	};
	sseClient.MessageReceived += m =>
	{
		Console.WriteLine(m.ToString());
	};
	Task T = sseClient.StartAsync(); // get task w/o awaiting so that it does not block
	Console.WriteLine("example work"); // do some work
	Console.ReadLine(); // now block until ready to stop streaming
	sseClient.Close();
}
