Japanese Translation Assistant

This is an embarrassingly ugly attempt to parse Japanese sentences using SudachiPy and print out the definitions of all of the words using JmDict, falling back to using Google Translate if no dictionary entry exists. The entire sentence is also translated using Google Translate to give the reader a guide on what sorts of word senses to be looking for. Although Google Translate is notoriously bad at Japanese to English translation, it can sometimes be helpful.
