/// 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.
