Detailed Description

Specialization of RecursiveASTVisitor that visits those nodes that are relevant to the dataflow analysis; generally, these are the ones that also appear in the CFG.

To start the traversal, call TraverseStmt() on the statement or body of the function to analyze. Don't call TraverseDecl() on the function itself; this won't work as TraverseDecl() contains code to avoid traversing nested functions.
