Outdated documentation on the web page

[ThomasEwaldETH]

Hello there,

I was using the pymoo module recently, and I discovered, that the documentation on the termination classes is outdated a bit. I am specifically talking about the Objective Space Tolerance section (I didn't check the other ones).
It was a bit confusing for me, however, with the help here on GitHub and a closer look into the class files I figured out what to do. Nevertheless, future users may encounter the same problem.

Best regards and thanks a lot for this great optimization module
Thomas
