ChipAttributes class abstract interface

An interface defining the base attributes for a Material Design chip.

Chips are compact elements that represent an attribute, text, entity, or action.

The defaults mentioned in the documentation for each attribute are what the implementing classes typically use for defaults (but this class doesn't provide or enforce them).
