class makVrv::DtNTree< T, Dimensions, Mutex, SubcellTraits, BoundsType >

Generate NTree (binary tree, quadtree, octree, etc.) class.

This consists of the tree itself and a query class which is a general search algorithm. The tree itself is a container and has very little functionality. In the nomenclature of this class, a tree has a number of subcells, each of which has a pointer to itself own (sub)tree, although that poitner can be empty if the subtree hasn't been created yet. Trees are independent of each other, while subcells are part of a tree. Trees are always managed by shared pointers. The shared/weak pointer policies control the ownership semantics of the trees. The shared policy (default) has the subcells owning their subtrees, so they are never automatically removed. The weak pointer policy has subcells holding their subtrees with weak pointers. This means that the users must save shared pointers to the subtrees that they want to keep in existence. If this is done then when the last reference to the subcell is removed, the subcell will automatically be removed from the tree without any further work.

These functions allow shared and weak pointers to be treated the same.

Weak pointers cannot be directly converted into shared, lock() must be called.
