   *  @history 2007-02-13 Tracie Sucharski,  Open cube read, not read/write.
   *                          Opening read/write was done to accomodate the
   *                          EditTool. EditTool will now reopen the cube
   *                          read/write.
   *  @history 2008-05-27 Noah Hilt, When opening a cube now if a
   *           user specifies extra arguments to the cube name,
   *           the cube will be opened using a CubeAttributeInput
   *           specifically for the number and index of bands to
   *           be opened. Additionally, if a cube is opened with 3
   *           bands it will be opened in RGB mode with red,
   *           green, and blue set to the 3 bands respectively.
   *  @history 2008-12-04 Jeannie Walldren - Removed "delete cube"
   *           since this was causing a segfault and this
   *           deallocation is already taking place in
   *           addCubeViewport(cube).
   *  @history 2015-05-13 Ian Humphrey - Caught exception now handled by sending a QMessageBox
   *                          to the Workspace. This prevents undefined behavior caused by not 
   *                          handling an exception within a connected slot.
   *  @history 2017-08-17 Adam Goins - Added the ability for this method to receive a cubelist
   *                          file as input to qview, parse out the .cub files from the
   *                          cubelist and then attempt to add each one into their own
   *                          viewport.
   *  @history 2017-10-12 Kristin Berry - Reverted to using relative instead of full file paths,
   *                          as this caused errors when working with cubelists that contained
   *                          relative paths. Fixes # 5177
