In our current explorations of syncing, it's useful to know if a TxReport represents a transaction that did nothing. Currently the only way to do find this out is by querying a transactions table after the fact. A simple way to represent this state would be with a simple flag on the TxReport - but perhaps we'd want to know more information about what a transaction did at some point - hence the counts.

This assumes that we'll be using transactor for syncing purposes beyond initial prototyping.
