incompatible with Julia 1.0

Just tried to run one of the examples (awesome work! thank you for developing this package!) and the import StochDynamicProgramming gives:

Here is my output from versioninfo():

julia> versioninfo()

I don't know enough about Julia to know if this is related to #163, however my version of JuMP is less than 0.19:

julia> Pkg.installed()
Dict{String,Union{Nothing, VersionNumber}} with 6 entries:
  "Juno"                    => v"0.5.3"

This package hasn't been updated to Julia v1 yet. If you need it, you should install Julia v0.6.

[NLaws]

@odow ok thanks for the response. Good to know the compatible Julia version so that I can start working with the package.

Other options you could look into are https://github.com/JuliaStochOpt/StructDualDynProg.jl, which I think has been updated to Julia 1.0 (@blegat?); https://github.com/odow/SDDP.jl. which only works on Julia 0.6; and https://github.com/odow/Kokako.jl which only works on Julia 1.0 and is under development (and not documented well), but includes cool things like being able to solve infinite horizon problems.

Yes :)

[NLaws]

Awesome. Thanks so much for the knowledge.

I am planning to update StochDynamicProgramming to julia 1.0+ and JuMP 0.19. Hope that we will able to release soon!

Need any help? 😃

Solved with #173
