10 /// This file implements an ASTConsumer for consuming model files.
11 ///
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.
