CONTRIB-497 *Added more visualizations *Added selector UI Widget for flex/flare visualization *Refactored some of flex actionscript code. *Added defaults for selected group and items in visualizations. *Improved removal of nodes and edges when an item or group is deselected in a legend. *Fixed a memory leak realting to the removal and addtion of nodes. *Added more options for and control of the flex/flare based visualization from the Moodle back end.
