/// \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.
