Implement Openskill as an alternative to Truskill

[eullerpereira94]

Hi, in the recent years (2011 to be precise), a team of Taiwanese researchers published a paper about an alternative method to online ranking through a Bayesian approach, just like Truskill. It has the same concepts of perceived skill and variance, but is completely patent and trademark free. Currently, there isn't a Ruby implementation, but the the algorithm has been implemented under the name Openskill in several languages, like Javascript, Python, Elixir, Lua, Kotlin, and even one in Go by yours truly.
I'm not asking for you to start immediately start implementing this algorithm, hell, I might even do it some day. What I'm suggesting is that you keep this idea in the back burner, for maybe, whenever you feel like, add this rating method to Elovation.

Thanks for the information @eullerpereira94 I wasn't aware of this.

Given Truskill is patented and commercial - we only got soft approval from a representative at Microsoft that it isn't a problem, although if anyone uses this in a commercial sense then it is a problem.

Removing the Truskill implementation would be ideal as the approval is meaningless and its use is still a risk factor for users of this software. Moving to something like OpenSkill makes total sense, and would be an appropriate goal for this project if anyone reads this and is interested in taking it on.
