 # QuadTree motivation
 
-This repo implements a QuadTree (more correctly, an orthtree) in Rust. It is generic over the number of dimensions, the type of data stored, and the shape of the region being queried. Any struct that implements `Storable` can be inserted. When querying, pass in any region that implements `Query`.

Any struct that is `Storable` can be inserted. When querying, pass in any region that is `Query`. `Point` is automatically `Storable`
