Basics documentation example incorrect: sqrt >> isEven >> not

elm/core#1097

@lue-bird What do you think replacing 'sqrt' in the docs with round? round takes a Float and returns an Int. So it would make the example compilable:

round >> isEven >> not

Sounds good, maybe embedded in something like

[ 1.2, 3.7, -5.2, -10 ]
    |> Array.filter (round >> isEven >> not)
--> [ 1.2, -5.2 ]

(Btw, pinging me is fine but I have no more say or insight than you. I just happen to have been allowed to port all elm/ issues over)
