/**
    @class IVConnections 
  
       This class provides the connections between the ImageView GUI components
    made using QtDesigner and the classes that do the actual work for the
    ImageView.  It basically provides SLOTS that are called by the GUI 
   components' SIGNALS and in turn call methods on the ImageView 
   implementation objects.
