2022-12-23renaming core to chain and some other changesJSDurand
Some changes: - The core crate is renamed to "chain". - The crate "viz" is added, which will provide layered graph drawing algorithms. - A function is added to convert from a grammar to the regular language of its left-linear closures. - A function is added to convert from a nondeterministic finite automaton to its "null" closure. A null closure is the same automaton with edges added, as if some edges are "null". Whether an edge is null is determined by a function. Combined with the previous change, we can convert a grammar to the regular language of the null closure of its left-linear closures. --- Now it remains to test more grammars and add an Atom trait, before finishing the part about compilations.

2022-11-15Initial commitJSDurand
Basic GNU standard files are added, and we now stop worrying about monadic anamorphisms. The current focus is on testing the correctness of the algorithm, so I need convenient support for manipulating, interpreting, examining, and per chance animating nondeterministic automata.
