TsvSampleOptions

Container for command line options and derived data.

TsvSampleOptions handles several aspects of command line options. On the input side, it defines the command line options available, performs validation, and sets up any derived state based on the options provided. These activities are handled by the processArgs() member.

Once argument processing is complete, the TsvSampleOptions is used as a container holding the specific processing options used by the different sampling routines.
