Dashboard chart changes

[gautamrege]

Details are mentioned below the tasks.

• The drop down should have "Team Commits", "Team Scores", "Individual Commits"
• There should be a button "Publish Results".
• Progressive Chart should be visible without authentication and we should be able to embed on intranet.

Team Scores

See ticket #2 for details on how scores are created. The chart should reflect team scores.

Publish Results

See ticket #3 for details on Snapshot. When we click "Publish Results" (seen only by admin), a complete snapshot of scores, commits, team distribution etc. is taken and put in a separate table for the duration and marked as completed i.e. one round on the competition is over.

Progressive Chart

See ticket #4 for details. This is the chart where we can see based on published results. This chart has a dropdown for selecting rounds and we can see how the team scores and individual scores have progressed over time.
