[ChrisRackauckas]

tests are using DiffEqBiological but should be using Catalyst.

@korsbo ?

[vtjnash]

bump?

Hadn't seen that heh

[gustaphe]

Sorry about the delay in replies here. I'd be comfortable merging either of this or #245, but I don't know if there is any difference apart from a couple of style choices. Can any of you spot anything?

[gustaphe]

Closed with #245
