2011-06-27 Steven Lambright - Added addCachingAlgorithm()
2011-07-18 Jai Rideout and Steven Lambright - Added unimplemented copy constructor and assignment operator.
2011-07-18 Jai Rideout and Steven Lambright - getDataFile() is no longer const, along with readRaw() and writeRaw().
2011-11-23 Jai Rideout - Added fix to findCubeChunks() and findIntersection() so that requested areas that are outside of the virtual bands of the cube will no longer fail, but instead will fill the buffer with nulls.
2012-02-17 Steven Lambright - The read() method is now const - the caching should be transparent to the API. It is still important to note that you cannot call read() and write() simultaneously - Cube is guaranteeing this. Backgrounded writes are now implemented and fully supported. Timing tests show results like this: Before: User: 358.71 Kernel: 38.29 Total Elapsed: 6:49.83 After: User: 380.01 Kernel: 44.97 Total Elapsed: 6:19.96 User- user-space CPU time consumed. Kernel- kernel-space CPU time consumed. The CPU consumption and kernel time consumption goes up, but the overall run time is lower. This makes the option perfectly viable for typical multi-core desktop solutions. Turning off the cube write optimization results in equivalent run times as before implementation. These time tests were run before the adaptive cache flush size was added, which improved performance further. References #727.
2012-06-06 Jeff Anderson - The read() method was modified to improve the speed for small buffer sizes as seen in ProcessByBoxcar and ProcessRubbersheet. The internal cache was always checked to be minimized which is slow for every read. Now the cache is only mimimized if it changed in size. Reference #894.
2014-04-07 Kimberly Oyama and Stuart Sides - Modified the findCubeChunks, writeIntoDouble, and writeIntoRaw methods to handle repeating virtual bands. Fixes #1927.
2014-09-30 Ian Humphrey - Modified read method to correctly access virtual bands when cube dimensions and buffer shape are same size. Fixes #1689.
2015-01-30 Ian Humphrey - Modified destructor to free m_writThreadMutex to prevent memory leaks upon destruction. Fixes #2082.
2016-04-21 Makayla Shepherd - Added UnsignedWord pixel type handling.
2016-06-21 Kris Becker - Properly forward declare QPair as struct not class
2016-08-28 Kelvin Rodriguez - updateLabels now a pure virtual, it had no implementation causing warnings in clang. Part of OS X 10.11 porting. QPair forward declaration now properly claims it as a struct.
2017-09-22 Cole Neubauer - Fixed documentation. References #4807
2018-07-20 Tyler Wilson - Added support for unsigned integer special pixel values. in functions writeIntoRaw(...) and writeIntoDouble(...) References #971.
2018-08-13 Summer Stapleton - Fixed incoming buffer comparison values for unsigned int type in writeIntoRaw(...).
