Colormouse

Colormouse adds a toggle button to the figure window which allows dynamic mouse control of the color axis. When the button is toggled, clicking an object and moving the mouse while the mouse button is held will change both the range and offset of the colorscale. This enables easily finding a color axis that best suits the data.
The colormouse toggle button also creates a context menu for the figure which allows the selection any of MATLAB's default colormaps.
