Use Requires in XFZ18

[mforets]

The uuids are these:

function __init__()
     @require MultivariatePolynomials = "102ac46a-7ee4-5c85-9060-abc95bfdeaa3" begin
        @require DynamicPolynomials = "7c1d4256-1411-5781-91ec-d7bc3513ac07" begin
            @require JuMP = "4076af6c-e467-56ae-b986-b466b2749572" begin
                @require PolyJuMP = "ddf597a6-d67e-5340-b84c-e37d84115374" begin
                    @require SumOfSquares = "4b9e565b-77fc-50a5-a571-1244f986bda1" begin
                        @require MathOptInterfaceMosek = "0087ddc6-3964-5e57-817f-9937aefb0357" begin
                            @require SemialgebraicSets = "8e049039-38e8-557d-ae3a-bc521ccf6204" begin
                                include("XFZ18.jl")
                            end
                        end
                    end
                end
            end
        end
    end
end # function

Proposal:

function __init__()
    @require MultivariatePolynomials = "102ac46a-7ee4-5c85-9060-abc95bfdeaa3" load_MultivariatePolynomials()
    @require DynamicPolynomials = "7c1d4256-1411-5781-91ec-d7bc3513ac07" load_DynamicPolynomials()
    @require JuMP = "4076af6c-e467-56ae-b986-b466b2749572" load_JuMP()
    @require PolyJuMP = "ddf597a6-d67e-5340-b84c-e37d84115374" load_PolyJuMP()
    @require SumOfSquares = "4b9e565b-77fc-50a5-a571-1244f986bda1" load_SumOfSquares()
    @require MathOptInterfaceMosek = "0087ddc6-3964-5e57-817f-9937aefb0357" load_MathOptInterfaceMosek()
    @require SemialgebraicSets = "8e049039-38e8-557d-ae3a-bc521ccf6204" load_SemialgebraicSets()
end

function load_MultivariatePolynomials()
    initialize_XFZ()
end

function load_DynamicPolynomials()
    initialize_XFZ()
end

function load_JuMP()
    initialize_XFZ()
end

function load_PolyJuMP()
    initialize_XFZ()
end

function load_SumOfSquares()
    initialize_XFZ()
end

function load_MathOptInterfaceMosek()
    initialize_XFZ()
end

function load_SemialgebraicSets()
    initialize_XFZ()
end

function initialize_XFZ()
    if isdefined(@__MODULE__, :MultivariatePolynomials) &&
            isdefined(@__MODULE__, :DynamicPolynomials) &&
            isdefined(@__MODULE__, :JuMP) &&
            isdefined(@__MODULE__, :PolyJuMP) &&
            isdefined(@__MODULE__, :SumOfSquares) &&
            isdefined(@__MODULE__, :MathOptInterfaceMosek) &&
            isdefined(@__MODULE__, :SemialgebraicSets)
        eval(load_XFZ())
    end
end

Then in the code you wrap everything as follows:

function load_XFZ()
return quote
...
end  # quote
end  # function
