* \class eVisGenericEventBrowserGui
48
* \brief Generic viewer for browsing event
49
* The eVisGenericEventBrowserGui is simply a window that will display an image referenced/stored
50
* in an attribute of a feature. Images can either loaded locally from disk or loaded via a URL.
51
* The eVisGenericEventBrowserGui also interacts with the map canvas to draw a highlighing symbol
52
* on the canvas. The highlighing symbol can also be a pointer showing the direction in which the
53
* image was taken by referencing a compass bearing recorded as an attribute of a feature.
