Widget used for display and analysis of image data.
Implements many features:
* Displays 2D and 3D image data. For 3D data, a z-axis
slider is displayed allowing the user to select which frame is displayed.
* Displays histogram of image data with movable region defining the dark/light levels
* Editable gradient provides a color lookup table
* Frame slider may also be moved using left/right arrow keys as well as pgup, pgdn, home, and end.
* Basic analysis features including:
