:estimator:
The estimator element is used to force the use of either ``analog`` or
``tracklength`` tally estimation. ''analog'' is generally less efficient
though it can be used with every score type. ''tracklength'' is generally
the most efficient, though its usage is restricted to tallies that do not
score particle information which requires a collision to have occured, such
as a scattering tally which utilizes outgoing energy filters.
The estimator element is used to force the use of either ``analog``,

the least efficient though it can be used with every score type.
``tracklength`` is generally the most efficient, but neither ``tracklength``
nor ``collision`` can be used to score a tally that requires post-collision
information. For example, a scattering tally with outgoing energy filters
cannot be used with ``tracklength`` or ``collision`` because the code will
not know the outgoing energy distribution.
