The paragraph explaining how each AST node class had its own overloaded hook in RecursiveASTVisitor didn't seem very clear to me. Reworked it in an attempt to be more explicit on what's actually happening.

 Now that everything is hooked up, the next step is to implement a
 RecursiveASTVisitor to extract the relevant information from the AST.
-The RecursiveASTVisitor provides hooks of the form bool
-VisitNodeType(NodeType \*) for most AST nodes; the exception are TypeLoc
-nodes, which are passed by-value. We only need to implement the methods
-for the relevant node types.
+If you wish to extract AST nodes of class *NodeType*, you would overload
