    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?


    i dont think this import is necessary...


    nor this one

> 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.
