---------------------------
- Official release of Starsim!
- Adds a ``Calibration`` class, based on `Optuna <https://optuna.org>`_, to facilitate the calibration of Starsim models.
- Adds ``mean()``, ``median()``, and ``plot()`` methods to ``MultiSim``.
- Adds ``low`` and ``high`` attributes to ``Result`` objects.
- Adds a ``flatten()`` method to ``Results``, allowing nested ``Results`` objects to be turned into flat dictionaries.
- Removes duplicate UIDs among new infections, and adds a ``unique()`` method to ``ss.uids``.
- Fixes a bug that prevented ``ss.lognorm_im()`` from using callable parameters.
- Updates the default ``Sim`` string representation to be a single line; the more verbose version is available via ``sim.disp()``.
