You can now create a LedgerEntrySet without a TransactionEngine. You can

call all the various entry* functions on it directly. You can throw it out
when you're done. The constructor is:

    LedgerEntrySet(Ledger::ref ledger)

All the normal checkpointing, caching, and swapping will work. Of course,
you cannot commit the results. The TransactionEngine::entry* functions now
just directly call the corresponding functions on the LedgerEntrySet. You
can call them in code that will only be used in the context of a
transaction.
