New LR1/LALR parser generator "rustlr"

For those of you seeking a Yacc-like parser generator in and for Rust, rustlr has been available and now the tutorial has enough chapters and examples to explain most of its features. I was trying to create a tool that's similar to Yacc. The parser generator has, for example, the ability to interactively train the parser to give helpful error messages.
