Onboarding: diagram that shows how exercism works

[kytrinyx]

Last year @studiolo played around with some ideas about creating a diagram for how Exercism works.

I think that this could help in the onboarding process to give people an idea of where they're headed.

I like the idea of this, and would want to emphasise the human aspects of the site more.

The original discussion is here: exercism/problem-specifications#82

If you center the down arrow and flip the right circle arrow to counter-clockwise, I think it'll give a more "physical" impression.

I do think a graphic is super helpful in illustrating what exercism is about, and I agree @kytrinyx it would be great to emphasise the human/community aspects more, along with that new little known nugget of:

• submit your code
• learn from the community by seeing how they completed the same problem
• receive feedback

We're doing a complete overhaul as described in #113 and #154, which will include a brand new onboarding experience.
