formgram 0.0.6

Formgram is a toolkit for teaching and or learning formal grammars with a focus on exploring the code and experimenting with and on it.

Students can use it to verify their findings in exercise problems and to understand taught algorithms by looking at their implemented form (and experimenting on them to see where those might break).

Teachers can use it to teach algorithms in their implemented form as an alternative to pure mathematical pseudocode.
