 Abstract: A sample to demonstrate tracking of background mouse, keyboard and tablet 

    events using the EventMonitor API which is available in OS X 10.3.x and later.

    In order to track keyboard events, you must "Enable access for assistive devices"

    in the Universal Access Control Panel. There is no programmtic means to enable/diable

    this setting automatically. This sample can compile as a Universal Binary.

    To use this program, first open a Console window, then Launch this sample application and 

    in the dialog box, check the types of events that you want to be logged. 

    While this sample application is in the background all selected keyboard, mouse and

    tablet events will be logged to the console window.
