Train flux struct with list of models

    function GlobalModel()
        model1=Chain(Dense(3=>3,bias=false,init=rand))
        model2=Chain(Dense(3=>1,bias=false,init=rand))
        subnets=[model1,model2]
        new(subnets)
    end

Move this inner constructor outside of the definition of GlobalModel. Then instead of new, just call GlobalModel(subnets). The general recommendation is to avoid inner constructors unless you need them, and in this case you don’t
