  \class PolyUncompressor

  \brief The PolyUncompressor class is a class for uncompressing

  compressed files.

  This subclass of Uncompressor contains a parameterized

  command for doing the uncompression

  It has an uncompressFile() function you call to do the

  actual uncompression.

 */

/*!

  The constructor takes the list of filename \a extensions,

  which it passes to the base class, and the \a commandFormat,

  which it stores locally. The \a commandFormat is a command

  template string.

 */

/*!

  From \a filePath, derive a file path for the uncompressed

  file and return it. If it can't figure out what the file

  path should be, it just concatenates ".out" to the

  \a filePath and returns that.

  the executeCommand() function to do the work. That's all it does.
