When the first instance of this class is created, it calls initialiseJuce_GUI(),

and when the last instance is deleted, it calls shutdownJuce_GUI(), so that you

can easily be sure that as long as at least one instance of the class exists, the

library will be initialised.
|
|

This class is particularly handy to use at the beginning of a console app's
|
|
main() function, because it'll take care of shutting down whenever you return
|
|
from the main() call.
|
|
|

Be careful with your threading though - to be safe, you should always make sure
|
|
that these objects are created and deleted on the message thread.
