streamSub - Subset streamlines

Extract a subset of streamlines from a streamline file, based on one of a set of user-selectable criteria (random sampling, physical location of the streamline seed point, etc). This process will discard the connectivity info of the streamlines. Typically, this tool is used to extract a manageable number of lines for quick plotting in order to get a feel, or gather statistics, for the data contained in the full set.
