LifeCycle of flex application: 
When we create a flex application in Adobe flash builder 4 the following event
sets the lifeCycle of flex application. 
1. preInitialize: mx.core.UIComponent.preinitialize 
Dispatched at the beginning of the component initialization sequence. The
component is in a very raw state when this event is dispatched. Many components,
such as the Button control, create internal child components to implement
functionality; for example, the Button control creates an internal UITextField
component to represent its label text. When Flex dispatches the preinitialize
event, the children, including the internal children, of a component have not
yet been created. 
Event Type: 
mx.events.FlexEvent.PREINITIALIZE 
 
2. initialize: mx.core.UIComponent.initialize 
Initializes the internal structure of this component. Initializing a UIComponent
is the fourth step in the creation of a visual component instance, and happens
automatically the first time that the instance is added to a parent. Therefore,
you do not generally need to call initialize(); 
 
3. creationComplete: mx.core.UIComponent.creationComplete 
Dispatched when the component has finished its construction, property
processing, measuring, layout, and drawing. At this point, depending on its
visible property, the component is not visible even though it has been drawn. 
Event Type: 
mx.events.FlexEvent.CREATION_COMPLETE 
 
4. applicationComplete: spark.components.Application.applicationComplete 
Dispatched after the Application has been initialized, processed by the
LayoutManager, and attached to the display list. 
Event Type: 
mx.events.FlexEvent.APPLICATION_COMPLETE
