/*:
## Phone Words

Generate a collection of words that can be represented by a given phone number. If a phone number contains the digits `1` or `0` then split up the phone number and find the words for each of the substrings as long as each substring has more than one digit. Non-keypad characters can be ignored. Optionally, filter out words so that only dictionary words are present in the result.
