Code/HumanoidRetargeter/Core/Formats/Mmd/Bullet/BulletCollision/DbvtProxy.cs

A small class DbvtProxy used by the Bullet broadphase implementation. It stores a reference to a DbvtNode leaf, a pair of link slots, and a stage integer, and exposes a property that sets m_leaf and contains a debugger check when the new leaf has no parent. It derives from BroadphaseProxy and initializes link slots in the constructor.
