+/// \file
+/// \brief This file implements an ASTConsumer for consuming model files.
+///
+/// This ASTConsumer handles the AST of a parsed model file. All top level
+/// function definitions will be collected from that model file for later
+/// retrieval during the static analysis. The body of these functions will not
+/// be injected into the ASTUnit of the analyzed translation unit. It will be
+/// available through the BodyFarm which is utilized by the AnalysisDeclContext
+/// class.
