Improvements to ROI presentation and UI support

[fedorov]

Right now, on this example, same color is applied, and it is impossible for the user to tell different kinds of ROI one from another

Additional ideas related to visualization of the individual regions:

• allow applying the same color all regions of the same semantics and allow toggling them all at the same time
• show ROI number/details in a tooltip as an option on mouse-over

Related suggestions from Javed Khan group communicated by @curtislisle:

• Each SR object belongs to a class (e.g. ERMS, ARMS, connective tissue, etc). Could it someday be added to have a way to enable or disable all the annotations of only a particular class simultaneously?

• it would be great to have the option of hovering over an object and having the class or a class nickname displayed.

• when selecting a particular object (by clicking on the right column), it would be nice to also be able to select by clicking a contour and seeing the corresponding entry in the column highlight.

• when an object is highlighted, it displays lighter than the rest. I think it would be more intuitive to make all non-selected objects become lighter instead.

• could we have different classes be displayed in different colors (or give a per color selector so the user could change colors at the class level.

Feedback from Tom G:

being able switch on ALL the ROI’s for a given class would be nice, eg, a button to just turn on all the stroma. Also, it seems like all the ROI’s are the same blue color. Differentiating by class would be helpful, ie necrosis = red; stroma = blue, etc.
