title: traits ui variable number of mayavi scenes and visualization of run time traits
body: <p>I would like to present the user with a variable number of scenes within the GUI (arranged say horizontally) composing different views of the data, depending on runtime conditions?</p>
  
  <p>I really don't want to redefine the GUI, and a number of scene related traits for every use case. (i.e. bool_scene_1_viewable=Bool(), bool_scene_2_viewable=Bool()... )</p>
  
  <p>It looks like I might be able to define a wildcard trait: scene_=Instance(Scene,()). But, if this is the best way to do it, how would I go about combining n traits into a View?</p>
