> Currently it's difficult to know, when issuing a filter, what percentage of
> rows were skipped by that filter. We should expose some basic counters back
> to the client scanner object. For example:
> - number of rows filtered by row key alone (filterRowKey())
> - number of times each filter response was returned by filterKeyValue() -
> corresponding to Filter.ReturnCode
> What would be slickest is if this could actually return a tree of counters
> for cases where FilterList or other combining filters are used. But a
> top-level is a good start.
