+/**
+ * Trying to explain the purpose of each route on the stack (ACTUALLY A STACK)
+ * Profile : To display the logged in user's profile when the userXId passed in to it is (undefined | null | empty string) else displays profile of the user being visited.
+ * Search : To display the search screen. Search for a user on this screen, click on a result tile and navigate to the same.
+ * When you click on the search icon after looking at a user's profile, the stack gets reset and you come back to the top of the stack (First screen : Search in this case)
+ * SocialMediaTaggs : To display user data for any social media account set up by the user.
+ * IndividualMoment : To display individual images uploaded by the user (Navigate to comments from this screen, click on a commenter's profile pic / username, look at a user's profile. Click on the profile icon again to come back to your own profile).
+ * MomentCommentsScreen : Displays comments posted by users on an image uploaded by the user.
+ * EditProfile : To edit logged in user's information.
