Detailed Description

Information about one declarator, including the parsed type information and the identifier.

When the declarator is fully formed, this is turned into the appropriate Decl object.

Declarators come in two types: normal declarators and abstract declarators. Abstract declarators are used when parsing types, and don't have an identifier. Normal declarators do have ID's.

Instances of this class should be a transient object that lives on the stack, not objects that are allocated in large quantities on the heap.
