/**
  @file
  @brief Creates a zip file
  @details For DIRECTORY usage, will ignore subfolders. For DATASET usage,
    provide a column that contains the full file path to each file to be zipped.

    %mp_zip(in=myzips,type=directory,outname=myDir)
    %mp_zip(in=/my/file/path.txt,type=FILE,outname=myFile)
    %mp_zip(in=SOMEDS,incol=FPATH,type=DATASET,outname=myFile)

  If you are sending zipped output to the _webout destination as part of an STP
  be sure that _debug is not set (else the SPWA will send non zipped content
  as well).
