## Text normalization

For [pepperino] search. i'm also planning to add bigrams and trigrams, which should be simple.

at the core of pepperino search is the `ReverseLookupMap`, which manages two mappings: `forward: Map>` and `backward: Map>`. adding(A, (1, 2, 3) to forward also adds 1 to A, 2 to A and 3 to A in the backwards map.
