by default if somehow the minTimeStamp gets kept as 0 with an empty
timestamps list, then it will filter _everything out_. Do you want to set this
to 0 and instead include everything by default? Might make it easier to debug
perhaps?

> In one of the use cases we were looking at, each row contains a single
> column, but with several versions (e.g., each version representing an event
> in a log), and we want to be able to extract specific set of versions from
> the row in a single round-trip.
> Currently, on a Get, one can retrieve a specific version of a column using
> setTimeStamp(ts) or a range of versions using setTimeRange(min, max). But not
> a set of specified versions. It would be useful to add this ability.
