dispatch and the target

Hi Mark,
I decided to try a more orthodox method of doing this.  The application now
includes a "start using" command for my library stack and the library stack
has a libraryStack message handler in it that does all the initialisation I
referred to.

However, the same problem still occurs, Referring to "the target" or "me" in
the libraryStack handler resolves to the library stack not the application
stack, which is consistant with how those keywords are defined in the
dictionary.  And because the libraryStack message does not allow for any
parameters, I cannot pass in the application stack's name.  I can use the
executionContexts to get the stack name of course but the dictionary claims
its format may change and it is not recommended to write code that depends
on its current format.

It appears there is no message path in these circumstances so I'm trying to
find a way to do what I need to do, absent the message path, not trying to
fight it.
