Update to v0.2 of MixedStructTypes

[Tortar]

Fixes #968 Fixes #967

I slightly changed the syntax in that package, and also solved some issues with the macros

[Tortar]

If I can kindly ask you George, can you give me your opinion on the syntax of https://github.com/JuliaDynamics/MixedStructTypes.jl? Do you think it is okay? :-)

[Tortar]

mmh actually again an instance of https://github.com/JuliaDynamics/Agents.jl/issues/963

Hi @Tortar I am available today. I Can review. But this still seems to be WIP, right? What would you like me to review from MixedStructTypes.jl?

[Tortar]

It should be ready for review now actually

[Tortar]

nevermind for MixedStructTypes.jl, it seems okay to me

[Datseris]

right, so what's the status now? what's the syntax, if it changed?

[Tortar]

No I mean no changes still to the syntax, will do that in a separate PR, I meant to say that the syntax changed in MixedStructTypes.jl and so I adjusted the macro to the new one

[Datseris]

Right. but what is the syntax change? It is not obvious to me by just looking at the readme.

[Tortar]

From e.g. :

@sum_struct_type @kwdef A{X} <: AbstractA{X} begin
           mutable struct B{X}
               a::Tuple{X, X} = (1,1)
               b::Tuple{Float64, Float64} = (1.0, 1.0)
           end
           mutable struct C
               a::Tuple{Int, Int} = (2,2)
               d::Int32 = Int32(2)
           end
           mutable struct D
               a::Tuple{Int, Int} = (3,3)
               const c::Symbol = :s
           end
           struct E{X}
               a::Tuple{X, X} = (3,3)
           end
       end

to:

@sum_structs A{X} <: AbstractA{X} begin
           @kwdef mutable struct B{X}
               a::Tuple{X, X} = (1,1)
               b::Tuple{Float64, Float64} = (1.0, 1.0)
           end
           @kwdef mutable struct C
               a::Tuple{Int, Int} = (2,2)
               d::Int32 = Int32(2)
           end
           @kwdef mutable struct D
               a::Tuple{Int, Int} = (3,3)
               const c::Symbol = :s
           end
           @kwdef struct E{X}
               a::Tuple{X, X} = (3,3)
           end
       end

In practice a shorter name for the macro and a finer control on kwdef (you can apply it to just some structs if you want)

This makes the macros even more similar to just write the structs and apply the macro afterwards

[Datseris]

right, but how is its application Agents.jl? do the subagents start with @subagent or not anymore? I guess its better if they don't? (I also find odd the usage of @kwdef . can you remove it?) I guess @kwdef is not in the Agents.jl version.

[Tortar]

No changes to the Agents.jl syntax were made, I haven't applied the new syntax @subagent, etc..., I will do it in another PR, so I think this PR is good to go as it is
