Summary

0028372: BVH_Tree class refactoring

Description

As discovered during review of fix for 0028368, current implementation of class BVH_Tree is confusing:

1. Structures BVH_BinaryTree (and BVH_QuadTree) and class BVH_TreeBase are defined not in the same-named headers but in BVH_Tree.hxx. This looks illogical. Note that in OCCT we have convention that a class should notmally be defined within the same-name header.

2. The names like BVH_Tree and BVH_BinaryTree are suggesting that the latter is successor of the former. This is not the case. Instead, BVH_Tree is dummy that has two specializations, while BVH_BinaryTree and BVH_QuadTree are just tags used to trigger specializations. It seems to be more straightforward just to define class BVH_Tree (or BVH_TreeBase) and two descendants, BVH_BinaryTree and BVH_QuadTree, providing relevant specializations.
