CSegmentCostCacheT - template class providing hash-map and storage (heap) of Tsegment structures.
Each rail node contains pointer to the segment that contains cached (or non-cached) segment cost information. Nodes can differ by key type, but they use the same segment type. Segment key should be always the same (TileIndex + DiagDirection) that represent the beginning of the segment (origin tile and exit-dir from this tile). Different CYapfCachedCostT types can share the same type of CSegmentCostCacheT. Look at CYapfRailSegment (yapf_node_rail.hpp) for the segment example
