+
+   A Stream object is something which accepts a stream of text.
+
+   The creation methods will vary on the type of Stream Object.  All creation
+   methods return a pointer to the stream type below.
+
+   As you can see, but the methods used to write to the stream and close it are
+   pointed to be the object itself.
