Add key differences between telemere and mulog to doc section

[velios]

Hello. First of all thx for the great tool.

I haven't had the opportunity to look into it in detail yet, but it all looks very interesting. Also, I couldn’t help but notice some parallels with mulog and I’m interested what key differences between telemere and mulog from your point of view. One of the things I was able to notice is clojure support, but i will be glad to read about another points.
