/** Gives access to the name of a window group and the information encoded by that 

name.

A window group is associated with a task, i.e. a running application. The 

window group's name encodes four pieces of information for that task:

the name of the document that the task is handling,

the task's caption,

the application specific UID, as eight hexadecimal characters,

status information for the task, as two hexadecimal characters.
