/**
 - MVC Pattern
 - Access Control Should be use in your code.
 - Code Commenting & Alignment.
 - Do not use lenghty funcion break them if you need.
 - String Property less then use
 - don't use repeated code
 - try to use genric's
 - create extension's, Helper  classes.
 - Each Controller should have denit method and cross check it call or not. if don't call thats means your class wouldn't go for ARC. There is strong property available.
 - You can use Subclasses for code cleaning and devidation in the particular section code. Like Header Subclass have own code, Same as Table Cell have on class code don't write the tableCell code in the controller. All Comments, I tried in my code.
