STREAM OBJECT DEFINITION
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.

Generic Error Stream
The Error stream simply signals an error on all output methods.
This can be used to stop a stream as soon as data arrives, for
example from the network.
