Tachyons: Flexbox Property Missing `flex:y`

[deadcoder0904]

flex:1 & flex:3 property is missing I think. Maybe I overlooked the documentation but it isn't there.

I need this too and created a Codepen example as to why:

I also wrote a test case: https://jsfiddle.net/ArthurClemens/5b9nLpu2/

I also need this. Here's another use case: http://codepen.io/anon/pen/mWMvKP

+1 on adding such class. For the sake of repetition, I also created a use case illustrating the reasoning behind it: https://codepen.io/elussich/pen/pdzpoW

@johnotander you might want to take a look at this issue again, now that you are reviewing all Flex classes.

Thanks!

Since flex is a composite property, I think it's better to have separate flex-grow-X, flex-shrink-X and flex-basis-X classes.
