Notes
-----
This may cannot be run more than once. NuclideBase instances are used throughout the ARMI
ecosystem and are even class attributes in some cases. Re-instantiating them would orphan
any existing ones and break everything.
Nuclide labels from MC2-2, MC2-3, and MCNP are currently handled directly.
Moving forward, we plan to implement a more generic labeling system so that
plugins can provide code-specific nuclide labels in a more extensible fashion.

force: bool, optional
If True, forces the reinstantiation of all :py:class:`INuclides`.
Any :py:class:`Nuclides <armi.nucDirectory.nuclide.Nuclde>` objects referring to the
original :py:class:`INuclide` will not update their references, and will probably fail.
