CONTRIB-497
Start of the grade/report/visual plug-in for displaying charts and graphs using flare as part of the GSoC animated grade statistics report project.

Currently only one visualization has been added and it is still in a rough state.

The code for the swf can be found in the flare_visualization dir.

Lots more work ahead to get the plug-in 100%.
