6 // Class TFoamCell used in TFoam
7 // ==============================
8 // Objects of this class are hyper-rectangular cells organized in the binary tree.
9 // Special algorithm for encoding relative positioning of the cells
10 // allow to save total memory allocation needed for the system of cells.
