Student performance visualization

[northdpole]

So far as part of the Challenge monitor controller we're gathering a bunch of data which could be a useful visualization of the user's progress and performance.

A nice feature would be to graph the data.

E.g. one could start from a bar graph of how much time did it take for each challenge to be solved by the user which also has an average.

@antonis-manaras Do you still have the notes we took during AppSec Project Summit on this?

I will have to check my notes, but in any case we can re-discuss it.

@antonis-manaras Okay! Ping us when you get it back.
