Add an ROI toolbar to your figure

This function adds an ROI toolbar to your figure.

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.
