Create Services

[ZakariaSaafi]

TODO

Create package named service including:

User Service Card Service Category Service Menu Service

Service is needed to synchronize between classes and relations where we can define our needed methods then call them 👍

FYI Service class contains only definition of methods for example :

public class UserService{

public void addUser(); public User updateUser(User user); public void deleteUser(User user); public List displayAllUsers();

}

Ingredient Service is created 👍
