Parser Prototype done

This week is been very productive, after a good explanation of how to build the AST, I manage to build the typed AST for MetaModelica, it means that the goals for the prototype are reached and now I can move to the next phase which is to build the Lexer Generator.

There are still things to do, like cleaning the code from unused variables and better performance of the loops, besides the error handling which is another major milestone in this project.
