Use @dispatch instead of branching for multiagent models

[Tortar]

Still a bit experimental in MixedStructTypes, so this still needs some adjustments, but I'd like to know what you think about this @Datseris (I'm still a bit unsure about the name of the macro). In practice what it does is to reconstruct the branching for the user. Actually in some more advanced cases, it could be more complicated to write the branching, with this it should be a lot easier.

[Datseris]

so what's the documentation? If I am a user wanting to learn, what do I read?

[Tortar]

Currently, there is a section in the ReadMe in MixedStructTypes describing it (https://github.com/JuliaDynamics/MixedStructTypes.jl?tab=readme-ov-file#define-functions-operating-with-the-mixed-structs) , but needs to be expanded.

In Agents.jl we probably need to add it to the tutorial when describing the multiagent macro.

[Datseris]

Okay, so this is a non-breaking addition that allows using a "multiple dispatch" like syntax for @multiagent. That seems totally fine for me. How aobut you give a shot at documenting this in the tutorial and we see how the final producct looks?

[Tortar]

Maybe this is good enough? I will wait a little bit before merging anyway because I need still to improve a bit more the macro

[Datseris]

I don't think it is a good idea to go all in into the @dispach. In general, keep in mind, macros are a concept that really only Julia uses from mainstream languages. Users coming from Java, C, Python, R, don't really use macros in typical user code. I think it is best if in the tutorial we first show the non-macro versions for everything, and then show the macro version and say "look, the macro version is created so that @multiagent is as harmonious as standard Julia multiple dispatch". (although, itself MD is also advanced concept that only Julia uses)

[Tortar]

Yes, I think you are right, I just demonstrated the branching version before the macro one now in the event-based tutorial. Now it should be good to go...but actually I still need to register the package so we need to wait a little bit more :D

[Datseris]

register which package? edit: okay saw the rename.
