A Simple React Date Picker Component

None of the existing open source react date picker components quite fit my requirements (mostly too bloated with too many dependencies), so I decided to see if I could quickly hack one together. This took a couple of hours, was easier than I thought it'd be, and meets my needs quite well. Most importantly, it's tiny (~100 LOC) and free of the complexity of many of the existing solutions.
