Add an ROI toolbar to your figure

This function adds an ROI toolbar to your figure.

Description

This function adds an ROI toolbar to your figure.
The ROIs are created using matlab buid-in class imroi.

addRoiToolbar: Add an ROI toolbar to the current figure.
addRoiToolbar(h): Add an ROI toolbar to the figure with a handle h.

Example 1:
   load mri;
   imshow(D(:,:,14));
   addRoiToolbar;
Example 2 (Multiple images):
   load mri;
   imdisp(D(:,:,1:8));
   addRoiToolbar;

Now draw some ROIs,and right click on one of them, you will see more functions in a context menu, such as:
   * change color
   * histogram
   * x-y plot
   * delete

Thanks to the "draggable" made by Francois Bouffard, you can drag around the textbox of ROI info.

imdisp is a nice tool to display multiple images in one figure, written by Oliver Woodford

I updated it to support the live update of histogram.

Thanks, nice function!

Is there a way you could add a live update for a plot or histogram?
