This version introduces significant improvements to make defining model point sets easier and more flexible:

- **No need to define model point sets in `input.py`** - if no model point sets are defined, a single calculation will be performed.
- **Flexible naming** - model point set no longer needs to be named `main`. Instead, for multiple sets, exactly one must have the `main` parameter set to `True` (e.g., `ModelPointSet(main=True)`).
- **Simplified `ID_COLUMN`** - the `ID_COLUMN` setting has been removed. Use the `id_column` parameter directly in the `ModelPointSet` class (e.g., `ModelPointSet(id_column=...`)).
- **Updated template** - the initial template now includes helpful comments to make getting started easier.

These changes reduce complexity.

This release introduces checks to ensure the settings are correct. It verifies that all settings are properly defined and that the output variables correspond to existing variables in the model.
