Add customizations to your line items and shipments.

A customization is made up of things:

• Customizable - the item (shipment or line item) that is being customized
• Article - the actual customization (i.e. text, image, etc)
• Configuration - responsible for defining the uniqueness of the customization
• Source - responsible for adjusting the item

An example:

A t-shirt can be customized with a graphic on the front and a line of text on the back.

Two "configurations", one representing the graphic, one representing the text. Two "articles", one representing the graphic, one representing the text. One "customizable", a line item.
