Median

[young (rtSwift)]

What’s the median of 0 and 1 as integers?

0.5

I think the median for Integer type should be a Double.

@beccadax

Is there something more general than FloatingPoint that we could require instead?

/ is separately defined in BinaryInteger and FloatingPoint. So median on collection need to be separately define on Integer type and FloatingPoint type.
