Multitree

Multitree is a way to store data in a computer so that it is easy to look up information. It's like a tree that has lots of different branches and leaves. Each branch has its own little tree on it, and each leaf has something unique and different inside it. When you want to find something, you can quickly search through each of the branches and leaves for something that you need.
