/*! \mainpage N-Dimensional Binary Trees This documentation describes how to use the n-dimensional binary tree C++ classes. The classes are all templated and behave similarly to the STL. Even though the class names all contain octree, they provide a generalization to any integer dimension. The octree class stores the root node of the tree plus information about the geometric embedding of the tree (if any). The octree_node class represents nodes in the tree and stores a pointer to the parent and child nodes plus a templated class instance of your choosing. Finally, octree_cursor and octree_iterator are subclasses of octree_path and provide a way to traverse the tree in either free-form or a depth-first fashion, respectively. */
