What is your license?

Hi Sven, thank you for your Binary Tree article article. It was the most clear, straightforward, and thorough explanation of binary trees I could find on the internet. The implementations of the various binary trees in this repository are also exceptionally clear and simple. I would like to use some of your code as the basis for an IntervalTree that I will make available under the MIT License. I could not find your license specification in this repository, and would therefore like to make sure I satisfy your requirements.
