BIF Parser

A lightweight lexer and parser for reading [Bayesian Interchange Format (BIF) files, implemented in modern C++. This tool parses Bayesian network models defined in .bif files, extracting network structure, variables, and probability tables into an internal abstract syntax tree (AST). It uses two main component: a very simple lexer, which uses for now std::regex to work and an hand written recursive descent parser in which I implemented the grammar from the site http://www.cs.washington.edu/dm/vfml/appendixes/bif.htm.
