+
+	13.10.16 - Addon receiver example created
+	14.10.16 - Included received frame rate
+	03.11.16 - Receive into image pixels directly
+			 - Add a sender selection dialog
+	05.11.16 - Note - dialog is Windows only
+			   the ofxNDIdialog class is used separately by the application
+			   and can be omitted along with resources
+	09.02.17 - Updated to ofxNDI with Version 2 NDI SDK
+			 - Added changes by Harvey Buchan to optionally
+			   specify preferred pixel format in CreateReceiver
