ptolemy.codegen.c.kernel.CParseTreeCodeGenerator

This class evaluates a parse tree given a reference to its root node. It implements a visitor that visits the parse tree in depth-first order, evaluating each node and storing the result as a token in the node. Two exceptions are logic nodes and the ternary if node (the ? : construct), which do not necessarily evaluate all children nodes.

This class has the following limitations:

It is a copy of ParseTreeCodeGenerator from data/expr and thus has lots of code for evaluating expressions, which we don't need
It is not properly converting types: We need to add logic to convert types.
The .tcl test has known failures involving nulls
It does not evaluate constants.
