Add tokenizer explain() debugging method (#4596) * Expose tokenizer rules as a property Expose the tokenizer rules property in the same way as the other core properties. (The cache resetting is overkill, but consistent with `from_bytes` for now.) Add tests and update Tokenizer API docs. * Update Hungarian punctuation to remove empty string Update Hungarian punctuation definitions so that `_units` does not match an empty string. * Use _load_special_tokenization consistently Use `_load_special_tokenization()` and have it to handle `None` checks. * Fix precedence of `token_match` vs. special cases Remove `token_match` check from `_split_affixes()` so that special cases have precedence over `token_match`. `token_match` is checked only before infixes are split. * Add `make_debug_doc()` to the Tokenizer Add `make_debug_doc()` to the Tokenizer as a working implementation of the pseudo-code in the docs. Add a test (marked as slow) that checks that `nlp.tokenizer()` and `nlp.tokenizer.make_debug_doc()` return the same non-whitespace tokens for all languages that have `examples.sentences` that can be imported. * Update tokenization usage docs Update pseudo-code and algorithm description to correspond to `nlp.tokenizer.make_debug_doc()` with example debugging usage. Add more examples for customizing tokenizers while preserving the existing defaults. Minor edits / clarifications. * Revert "Update Hungarian punctuation to remove empty string" This reverts commit f0a577f7a5c67f55807fdbda9e9a936464723931. * Rework `make_debug_doc()` as `explain()` Rework `make_debug_doc()` as `explain()`, which returns a list of `(pattern_string, token_string)` tuples rather than a non-standard `Doc`. Update docs and tests accordingly, leaving the visualization for future work. * Handle cases with bad tokenizer patterns Detect when tokenizer patterns match empty prefixes and suffixes so that `explain()` does not hang on bad patterns. * Remove unused displacy image * Add tokenizer.explain() to usage docs
