Added the option to buffer output before printing to `stdout`, which increases performance *drastically* for shell output (barely anything for direct-to-file)
`scripts/test_tokenizer.php` now uses `Parser`'s lexer. Profits from already-built token lists
`scripts/test_parser.php` and `scripts/test_tokenizer.php` now use more user-friendly stats
Adding empty newline at the end of Parser
Less mangling with arrays in `Tokenizer`
Improving the performance of `Tokenizer` by making `matchWildToken`'s perf `O(n)` (close to `O(1)` actually) instead of `O(n * m)`
Decreasing tokenization time for `mocks/lang/NewtonIteration` from 80-130ms to 45-75ms ;)
