This class is an abstract base class. Concrete subclasses must
define an __init__() that defines self.graph and then calls the
__init__() defined in this class.
The concrete class must also define the class attributes
NameFinder, FunctionGen, and ClassGen. These attributes can be
defined in the initClass() method, which is a hook for
initializing these methods after all the classes have been
defined.

The interpreter generates names that start with a period or
dollar sign. The symbol table ignores these names because
they aren't present in the program text.

The instruction is considered necessary if the node has a
lineno attribute and it is different than the last lineno
emitted.
Returns true if SET_LINENO was emitted.
There are no rules for when an AST node should have a lineno
attribute. The transformer and AST code need to be reviewed
and a consistent policy implemented and documented. Until
then, this method works around missing line numbers.

To generator code for augmented assignments, we use the following
wrapper classes. In visitAugAssign, the left-hand expression node
is visited twice. The first time the visit uses the normal method
for that node . The second time the visit uses a different method
that generates the appropriate code to perform the assignment.
These delegator classes wrap the original AST nodes in order to
support the variant visit methods.
