 As of two days ago, I had never attempted to write a Windows program. But I have been programming for about 35 years, and this is a simple program so it worked out just as I'd hope. I think it's working great, but if you find a problem create an issue in GitHub. 
 
 To make things a little easier on myself and keep this program simple, I took a shortcut in the way that the timer works. According to Microsoft, the type of timer that I'm using can be inaccurate by up to 57 milliseconds (57 thousands of a second). I don't expect it will make a difference for you if you're using this as a countdown for streaming software, but if you're trying to have a 48 hour countdown for a marathon or something, I imagine you will see a discrepancy by the end. I am unlikely to go back and make a version 2 of this, since I expect that I will be one of three people who download and use it. If I do go back into it, though, I will include Pause, Stop, and Reset buttons (which were not possible in the way that it's currently written.)
