While developing a Solution using Visualforce page and Apex, we have one common requirement which is to  show loading icon  whenever user click on button/link/panel etc. Few use case to show loading icon could be:       1.    Notify user that action he asked for is in progress. 2.    Don't want user to make any change till previous action finishes.
