2007-03-21 Tracie Sucharski - Changed call from fitScale to fitScaleMinDimension so that the minimum cube dimension is displayed in its entirety.
2008-05-27 Noah Hilt - Now allows cubes to be opened with additional arguments read by the CubeAttributeInput class, specifically to open certain bands as well as open 3 bands in RGB mode.
2008-12-04 Jeannie Walldren - Fixed bug in addCubeViewport(cubename). Added exception catch to addCubeViewport(cube) to close the CubeViewport from the ViewportMainWindow if it cannot be shown.
2009-03-27 Noah Hilt, Steven Lambright - Changed parent class from QWorkspace to QMdiArea since QWorkspace is now an obsolete class. Also changed how CubeViewports are created.
2010-04-08 Steven Lambright and Eric Hyer - Added progress bar
2010-06-26 Eric Hyer - Now uses MdiCubeViewport instead of CubeViewport. Also fixed include issues.
2010-11-18 Eric Hyer - addBrowseView now deletes the last viewport in the subWindowList instead of the first one
2011-09-19 Steven Lambright - Fixed addBrowseView to actually close the old viewports instead of hiding them. Fixes #418
2012-05-29 Steven Lambright - Now utilizes ViewportMdiSubWindow instead of QMdiSubWindow. References #854.
2012-09-18 Steven Lambright - Added the selfContained option to the constructor. This allows us to show a work space without handling the tool and status areas externally. No longer inherits from QMdiArea because of the need to place widgets around the mdi area.
2015-05-13 Ian Humphrey - Modified addCubeViewport(QString) to handle any exceptions that are thrown within the slot. This prevents undefined behavior when an exception is not handled within a connected slot. References #2210.
2016-09-08 Tracie Sucharski - Changed imageToMdiWidget to cubeToMdiWidget. Workspace deals with cubes. Since Image contains a cube, simply pass in cube instead of Image. This was done to handle the new IPCE container class, Shape, which also contains a cube, but not an Image.
2017-09-11 Adam Goins - Added the ability to accept cubelists under any file format. Fixes #5099.
2018-04-13 Christopher Combs - Added .lbl files to the list of single-cube file-extensions to check before reading a cube list in addCubeViewport. Fixes #5350.
2018-09-12 Adam Goins - Modified logic to attempt to open the file as a cube or detached label first, if that fails attempt to open it as a cube list and if that fails, throw an error to the user. This allows cubes and cube lists to be saved under any extension and opened. Fixes #5439, Fixes #5476.
