Modifiers, Modifier-groups (Add-ons & variants)

Modifiers are added to items, when they come in different options. Each combination of the modifiers, is an sell-able entity. 

The collective group of modifiers is called modifier-group. 

Now, modifiers-groups can be of two types: Variants or Add-ons

• Variants 
  These are modifier-groups that change the way an item is sold.
  
  For example, a Pizza item can have size as small, medium & large. These are three variants of the same Pizza item. Now when the customer select a variant of the Pizza item, it changes the way you sell the same Pizza item.
  
  
• Add-ons
  These are modifier-groups that are additional to the base item that is sold.
  
  For example, a Pizza item can have  toppings like Onions, Capsicum, Jalapenos, Chilis, Paneer etc. There are additional modifications that can be done to the base item. Now when the customer selects add-on(s), you sell the base item along with the additional add-ons selected.
