  12 /// This ASTConsumer handles the AST of a parsed model file. All top level
  13 /// function definitions will be collected from that model file for later
  14 /// retrieval during the static analysis. The body of these functions will not
  15 /// be injected into the ASTUnit of the analyzed translation unit. It will be
  16 /// available through the BodyFarm which is utilized by the AnalysisDeclContext
  17 /// class.
