"AppList" is a Cocoa sample application that demonstrates how to use the NSRunningApplication class provided by NSWorkspace.  NSRunningApplication can be used for inspecting and manipulating running applications on the system.  An array of these objects are by NSWorkspace using:
    NSArray *appList = [[NSWorkspace sharedWorkspace] runningApplications];
Only user applications can be tracked; this does not provide information about every process on the system.
Since NSRunningApplication has properties that vary, they can be observed with KVO.  So we use Cocoa bindings to display these properties to the user.  The properties are returned atomically so NSRunningApplication is thread safe.
Note: This app has been Sandboxed.
