 @class FBAppEvents

 @abstract
 Client-side event logging for specialized application analytics available through Facebook App Insights
 and for use with Facebook Ads conversion tracking and optimization.

 @discussion
 The `FBAppEvents` static class has a few related roles:

 + Logging predefined and application-defined events to Facebook App Insights with a
 numeric value to sum across a large number of events, and an optional set of key/value
 parameters that define "segments" for this event (e.g., 'purchaserStatus' : 'frequent', or
 'gamerLevel' : 'intermediate')

 + Logging events to later be used for ads optimization around lifetime value.

 + Methods that control the way in which events are flushed out to the Facebook servers.

 Here are some important characteristics of the logging mechanism provided by `FBAppEvents`:

 + Events are not sent immediately when logged.  They're cached and flushed out to the Facebook servers
   in a number of situations:
   - when an event count threshold is passed (currently 100 logged events).
   - when a time threshold is passed (currently 60 seconds).
   - when an app has gone to background and is then brought back to the foreground.

 + Events will be accumulated when the app is in a disconnected state, and sent when the connection is
   restored and one of the above 'flush' conditions are met.

 + The `FBAppEvents` class in thread-safe in that events may be logged from any of the app's threads.

 + The developer can set the `flushBehavior` on `FBAppEvents` to force the flushing of events to only
 occur on an explicit call to the `flush` method.

 + The developer can turn on console debug output for event logging and flushing to the server by using
 the `FBLoggingBehaviorAppEvents` value in `[FBSettings setLoggingBehavior:]`.

 Some things to note when logging events:

 + There is a limit on the number of unique event names an app can use, on the order of 300.
 + There is a limit to the number of unique parameter names in the provided parameters that can
 be used per event, on the order of 25.  This is not just for an individual call, but for all
 invocations for that eventName.
 + Event names and parameter names (the keys in the NSDictionary) must be between 2 and 40 characters, and
 must consist of alphanumeric characters, _, -, or spaces.
 + The length of each parameter value can be no more than on the order of 100 characters.

 track user acquisition and app install ads conversions.

 @discussion
 `activateApp` will not log an event on every app launch, since launches happen every time the app is backgrounded and then foregrounded.
 "activated app" events will be logged when the app has not been active for more than 60 seconds.  This method also causes a "deactivated app"
 event to be logged when sessions are "completed", and these events are logged with the session length, with an indication of how much
 time has elapsed between sessions, and with the number of background/foreground interruptions that session had.  This data
 is all visible in your app's App Events Insights.

 In some cases, apps want to use one Facebook App ID for login and social presence and another
 for App Event logging.  (An example is if multiple apps from the same company share an app ID for login, but
 want distinct logging.)  By default, this value is `nil`, and defers to the `FacebookLoggingOverrideAppID`
 plist value.  If that's not set, the default App ID set via [FBSettings setDefaultAppID]
 or in the `FacebookAppID` plist entry.

 This should be set before any other calls are made to `FBAppEvents`.  Thus, you should set it in your application
