Introduce shorthand properties

[pke]

I really like the minimalist approach of this lib after ditching material-ui.

I have a proposal to make the components even more easier to read:

Given the current state

<Flex
  align="center"
  justify="space-between"
  wrap={true}
>

What do you think about:

<Flex center space-between wrap>

Would that make sense?

A sorry, mixed up the projects. That should go to http://jxnblk.com/reflexbox/

Yeah I use shorthand booleans where appropriate (e.g. wrap). The docs are automatically generated from parsing jsx and it adds the true to props.

I tend to avoid booleans for potentially conflicting props like align and justify since they both have multiple possible values.
