Confirms if a word is in usr/share/dict/words.
(soon to be implemented) add the crate to [dependencies] and specify the lastest version. Then bring it into scope by placing extern crate words; followed by use words::* in a source file where the functionality is desired.
Go to /usr/share/dict/words and add all of those words to a vector of vectors. Then perform binary search on those words to confirm a query's existence.
