Dict is a spellchecking dictionar, that returns suggested words with levenstein distance 1 or 2 using it’s Dict::correction method.
It defaults to using the ASCII_LOWERCASE alphabet for it’s edits; see stringedits::Edit for more details on alphabets & edits.
All values in the dictionary are nonnegative integers; index access does not panic on a missing key,
but instead returns zero.
The default alphabet is ASCII_LOWERCASE; that is, ‘a..=z’
