Classes to allow line and column number information to stored in nodes. The LineNumberingNodeFactory stores line number information in nodes when they are created and the LineNumberingShuntingYard is part of the {@link com.singularsys.jep.configurableparser.ConfigurableParser} which stores line numbers during parsing. To setup you can use

Jep jep = new Jep(
  new StandardConfigurableParser(),
  new LineNumberingNodeFactory(),
  new LineNumberingShuntingYard.LineNumberGrammarParserFactory());

Line numbering starts from line 1 column 1.
