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;
Example 2 (Multiple images):
load mri;

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.
