copy dummy cache over implement retrievePackedPathFromSearchSpace calculate packed_path_from_source_to_middle debugging the retrievePackedPathFromSearchSpace function implementation adding in packed_path_from_source_to_middle cache is partway working unpack path and get duration that way the computeDurationForEdge method comment out cache clean up the code move vector creation and allocation to outside of loop hack to not return vectors on facade.GetUncompressedForwardDurations and facade.GetUncompressedReverseDurations clean up hack add exclude_index to cache key clearing cache with timestamp rebase against vectors->range pr swapped out unordered_map cache with a boost_lru implementation calculation for cache size cleaned up comment about cache size calculations unit tests cache uses unsigned char for exclude index clean up cache and unit tests
