This class is a much simpler implementation of Transcript protocol that supports multiple views and very simple conversion to morphic. Because it inherits from Stream, it is automatically compatible with code that is designe to write to streams.

	model protocol	top
	codePaneMenu:shifted: Note that unless we override perform:orSendTo:, PluggableTextController will respond to all menu items
	perform:orSendTo: Selector was just chosen from a menu by a user. If can respond, then perform it on myself. If not, send it to otherTarget, presumably the editPane from which the menu was invoked.
	release Remove references to objects that may refer to the receiver. This message should be overridden by subclasses with any cycles, in which case the subclass should also include the expression super release.
	step Objects that may be models of SystemWindows need to respond to this, albeit vacuously

	private	top

	stream extensions	top
	bs
	clear Clear all characters and redisplay the view
	endEntry Display all the characters since the last endEntry, and reset the stream
	flush Do nothing by default
	pastEndPut: If the stream reaches its limit, just output the contents and reset.
	show: TextCollector compatibility

	new Answer a new instance of the receiver (which is a class) with no indexable variables. Fail if the class is indexable.
	newTranscript: Store aTextCollector as the value of the system global Transcript.
