Detailed Description

Wraps a ledger instance for use in generic Validations LedgerTrie.

The LedgerTrie models a ledger's history as a map from Seq -> ID. Any two ledgers that have the same ID for a given Seq have the same ID for all earlier sequences (e.g. shared ancestry). In practice, a ledger only conveniently has the prior 256 ancestor hashes available. For RCLValidatedLedger, we treat any ledgers separated by more than 256 Seq as distinct.
