Creating Controllers

[prasanna1211]

Convert the logic in Server/common to be a class and controller. For example User controller can have

1. User.createUser
2. User.getByEmail

@prasanna1211 as you have mentioned using Object model for database models is a good practice to use. Right now I think our code has not reached that level of complexity. So we will keep this issue open until we implement that.
