Altered:
- Changed how range is handled in MPlotImages.  It is now the responsibility of subclasses to fill in the range rather than rely on the minMaxSearch.
- It has been tested.
- Only aspect to confirm is that the manual minimums and maximums stay and aren't overwritten.
Altered:
- Small changes mostly fiddling with MPlotColorLegend trying to get it to paint properly.
Altered:
- Modified the basic image.  Unsure if it works properly right now.
- Added a simple image data with default.  Unsure if it works yet.
