Create a branch containing the answers

[dayanyrec]

Hi!
I was in the last workshop and someone asked me how to see the answers to the proposed tasks in the repo. I think it would be a good idea maintain a branch in the repo containing the solved version, so people can refer to it to check and study their own answers. WDYT?

I created a branch called solution in my fork containing the solved version: https://github.com/dayanyrec/day-of-datomic-conj/tree/solution
