+In order to generate LLVM IR, we want some simple setup to get started.  First,
+we define virtual codegen methods in each AST class:</p>
+
+<div class="doc_code">
+<pre>
+/// ExprAST - Base class for all expression nodes.
+class ExprAST {
+public:
+  virtual ~ExprAST() {}
+  virtual Value *Codegen() = 0;
+};
+
+/// NumberExprAST - Expression class for numeric literals like "1.0".
+class NumberExprAST : public ExprAST {
+  double Val;
+public:
+  explicit NumberExprAST(double val) : Val(val) {}
+  virtual Value *Codegen();
+};
+...
+</pre>
