`create_sim`: functionality and naming consistency

[jpdunc23]

• Naming: We have many create_* functions that create R6 objects like the Experiment, DGP, and Method classes. On the other hand, we used init_docs() for setting up the Rmd documentation directory structure. I think renaming create_sim() to init_sim() would improve our API consistency. Another point of confusion is the hpc argument, which could mislead users into thinking that with hpc = TRUE their simulation will automatically work in a distributed computing environment (e.g., a Slurm cluster). I think we should rename this argument somehow to make it a bit more clear. Maybe scripts_dir (and also rename tests to tests_dir / add a logs_dir arg)? Another option (my preference) is to replace the hpc and tests args with an init_dirs argument that accepts string vectors, default c("logs", "scripts", "tests").
• Functionality: Can we have create_sim() optionally call init_docs() ? E.g., we could add a boolean argument init_docs.

Maybe create_sim() and init_docs() should be combined, somehow?

@PhilBoileau @tiffanymtang thoughts?

I like the idea of renaming create_sim() to init_sim().

Good points. Adding the described init_dirs sounds good to me.

I'm not sure if this is very natural. Currently, init_docs initializes the documentation for a simulation experiment created with create_experiment(). I think create_sim() initializes the directory structure for the overarching "project" or "study", which may consist of multiple simulation experiments. In some sense, maybe we should consider renaming create_sim() to init_sim_study() or init_study() or something of the like.
