Add a no-space model for comparison

[Datseris]

We can have a model that uses a network (with Graphs.jl) that implements a network-based version of the evolution model: https://juliadynamics.github.io/AgentsExampleZoo.jl/dev/examples/wright-fisher/

This allows us to create a model that has agent conections as graphs (which is oftren used), as well a sampling agents, which can be expensive, and replicating agentrs, which can also be expensive. We can also use the new replicate! function that didn't exist when the above example was written.

Alternatively, we could just drop the network connections alltogether if it makes the implementaTION too lengthy to implement in all softwares.
