vice.yields.sneia.settings.factory_settings
===========================================

Restores the SN Ia yield settings to their factory defaults. This
differs from ``vice.yields.sneia.settings.restore_defaults`` in that
users may modify their default values from those that VICE is
distributed with.

**Signature**: vice.yields.sneia.settings.factory_settings()

.. tip:: To revert your nucleosynthetic yield settings back to their
	production defaults *permanently*, simply call
	``vice.yields.sneia.settings.save_defaults`` immediately following
	this function.

Example Code
------------
>>> import vice
>>> vice.yields.sneia.settings["c"]
	0.0 # the user has modified their default yield for carbon
>>> vice.yields.sneia.settings.factory_settings()
>>> vice.yields.sneia.settings["c"]
