[cfe-dev] A small example on how to initiate header search and configure CFG from an already formed AST.

[Ted Kremenek]

It's optional, and you can leave it NULL.  It's there to support cross-translation unit analysis (in the future).

You can construct an AnalysisContext object using a FunctionDecl, and then call the getCFG() method to have it lazily create a CFG.  When the AnalysisContext object is destroyed, the CFG will be destroyed as well.
