/**
 * An AST node representing an identifier.
 * 
 * Identifiers may be short (such as width,
 * int, or public), dotted
 * (such as flash.display.Sprite), or parameterized
 * (such as {@code Vector.}).
 * 

 * Identifiers serve two purposes: in a declaration of a class, interface,
 * function, variable, constant, or namespace they provide the name
 * of the thing being defined; otherwise they provide a reference
 * to that definition.
 * 
 * In some cases, such as for packages and language identifiers,
 * the declaration is implicit rather than existing in source code
 * or in byte code.
