## What should be done to update this in the future?
1. Go to ekg/intervaltreerepository on GitHub.
2. Take the file IntervalTree.h wholesale and drop it into the directory here.
3. Don't change anything about it.
4. Validate that the license in the root of the repository didn't change and update it if so. It is sitting in the same directory as this readme.
If it changed dramatically, ensure that it is still compatible with our license scheme. Also update the NOTICE file in the root of our repository to declare the third-party usage.
