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.
