Show HN: Sherlock.js - natural language event parser

I wrote this Javascript library for parsing natural sentences into start and end dates for creating events a few weeks ago. It is designed for use in Tabule, which is a homework planner for students, so it is optimized for creating due dates.

I decided to open source the code to give back to the community and to find any holes in the parser that I may have missed. Let me know if you find a sentence that doesn't work! :)
