For 0.6, see [Broadcast for custom type - #3 by fengyang.wang](https://discourse.julialang.org/t/broadcast-for-custom-type/3497/3) for how to implement broadcast for a custom type. Note that a lot changes to `broadcast[!]` are coming in 0.7/1.0:

- [https://github.com/JuliaLang/julia/pull/23939](https://github.com/JuliaLang/julia/pull/23939) (improve ability to extend `broadcast` and properly document the process)
- [https://github.com/JuliaLang/julia/pull/24992](https://github.com/JuliaLang/julia/pull/24992) (improve ability to extend `broadcast!` and avoid ambiguities between packages in similar fashion)
- [https://github.com/JuliaLang/julia/pull/23692](https://github.com/JuliaLang/julia/pull/23692)
