freezeColors v2.5; 7/2022

freezeColors allows multiple colormaps to be used per figure and even within a single axis.

2022 Changes (v. 2.5)

* greater emphasis on multiple colormaps within a single axis
* new method for freezing colorbars
* scatter works properly
* works properly when calling freezeColors(axesHandle)
* includes a replacement for colorbar: jicolorbar

Prior History

 * In 2005 freezeColors was written to enable multiple colormaps in a single figure, something MATLAB could not do.
 * In 2014, MATLAB enabled each axis to have its own colormap.
 * Over time, as MATLAB graphics evolved, freezeColors stopped working in some situations. Now it's back.
