Create Wizard flow using angularjs without routing

It often is the case that we want to toggle between views based on the choice the user has made. Also, if the user switches from one choice to other, we should be able to hide the current view and show the new based on the selection made. To ease the process of hiding and showing the panels based on the choice made by the user, I have created a directive to help us with the same. Its another way of implementing routing for small components.
