* db based version of PrefixByCumulativeWitnessSize
* db based version of PrefixByCumulativeWitnessSize
* retain all in Trie by default
* fix WitnessLen logic in calcTrie roots
* Rename IntermediateTrieWitnessLenBucket to IntermediateWitnessLenBucket
* handle corner cases in WL
* Use correct incarnation for IH bucket
* use name WitnessSize
* save progress towards db-only witness estimation
* results from trie and from db are still different
* less recursion
* correct incarnation in CumulativeSearch
* reuse results from previous Tick, separate concepts of parent and startKey
* experiment: if not including trie structure to WitnessSize will reduce cumulative error
* tool to generate all IH and tool to calculate assessment of cumulative error
* tool to generate all IH
* Calculate totalWitnessSize based on DB data - then schedule will not overrun state during MGR cycle
* better stats
