Add "isInitialized" method to the Qubit SDK class

[menardsmobileapp]

The QubitSDK class should have an isInitialized() method. Something simple like

public static boolean isInitialized() {
    return sdkSingleton != null;
}

This would make it easier to temporarily disable Qubit, or to defer its initialization to the first activity when no custom Application class is being used.

@menardsmobileapp if you would like to disable sdk to send events there is flag in EventTracker interface called enable you can switch it off/on
