Subject: Apply rule-of-zero to delete standard methods where possible as
 handled by contained types. This allows flexibility as most lower-level data
 types can be moved and SplitVector and Partitioning of non-move-only types
 may be copied. CellBuffer still needs destructor due to incomplete type so
 retains all standard operations.
