Overload broadcasting behavour

[oxinabox]

Target functionality

I often find myself writing functions that take a Model and either s Species or a Reaction etc.
And I want to broadcast this across a list of reactions.
foo.(model, rs)

Optional: Suggestions for implementation

Broadcast.broadcastable(x::Model) = Ref(x)
Broadcast.broadcastable(x::Species) = Ref(x)
Broadcast.broadcastable(x::Reaction) = Ref(x)

etc

oh nice so this is the way to avoid writing Ref everywhere that I was looking for... :D I'll try to do asap, if you have any working code please feel free to PR even if half-baked or so.

Q: Is there some docs that guarantees how supported/sustainable/portable this is w.r.t. julia stdlib? The docs here https://docs.julialang.org/en/v1/manual/interfaces/#man-interfaces-broadcasting are the only authoritative ones, right? If I get it right, these basically say that your oneliners (one per struct type) are completely sufficient, right?

This is indeed part of the julia public API.
There potentially is some suggestion that it should be written:
Broadcast.broadcastable(x::Model) = (x,)
but it is much of a muchness

You can also do it with a union

Broadcast.broadcastable(x:Union{Model, Species,Reaction,...}) = Ref(x)

@oxinabox I'll release this shortly, dependency for this should be 1.7
