 * onNativeReady              Internal event that indicates the PhoneGap native side is ready.
 * onPhoneGapInit             Internal event that kicks off creation of all PhoneGap JavaScript objects (runs constructors).
 * onPhoneGapReady            Internal event fired when all PhoneGap JavaScript objects have been created
 * onPhoneGapInfoReady        Internal event fired when device properties are available
 * onDeviceReady              User event fired to indicate that PhoneGap is ready
 * onResume                   User event fired to indicate a start/resume lifecycle event
 * onPause                    User event fired to indicate a pause lifecycle event
 * onDestroy                  Internal event fired when app is being destroyed (User should use window.onunload event, not this one).
