Perform any setup steps necessary before running the skim. This may include:
* applying event-level cuts using `ifEventPasses`,
* adding the `MCMatcherParticles` module to the path,
* running the FEI.
Warning:
Standard particle lists should *not* be loaded in here. This should be done
by overriding the method `BaseSkim.load_standard_lists`. This is crucial for
avoiding loading lists twice when combining skims for production.
Parameters:
path (basf2.Path): Skim path to be processed.
Reimplemented from BaseSkim.

Apply event-level cuts in a skim-safe way.
Parameters:
cut (str): Event-level cut to be applied.
path (basf2.Path): Skim path to be processed.
Returns:
ConditionalPath (basf2.Path): Path on which the rest of this skim should be
processed. On this path, only events which passed the event-level cut
will be processed further.
.. Tip::
If running this function in `BaseSkim.additional_setup` or
`BaseSkim.build_lists`, redefine the ``path`` to the path returned by
`BaseSkim.skim_event_cuts`, *e.g.*
.. code-block:: python
def build_lists(self, path):
path = self.skim_event_cuts("nTracks>4", path=path)
# rest of skim list building...
.. Note::
The motivation for using this function over `applyEventCuts` is that
`applyEventCuts` completely removes events from processing. If we combine
multiple skims in a single steering file (which is done in production), and
the first has a set of event-level cuts, then all the remaining skims will
never even see those events.
Internally, this function creates a new path, which is only processed for
events passing the event-level cut. To avoid issues around particles not
being available on the main path (leading to noisy error logs), we need to
add the rest of the skim to this path. So this new path is assigned to the
attribute ``BaseSkim._ConditionalPath``, and ``BaseSkim.__call__`` will run
all remaining methods on this path.

Add the module `skimExpertFunctions.InitialiseSkimFlag` to the path, which
initialises flag for this skim to zero.
.. Warning::
If a conditional path has been created before this, then this function
*must* run on the conditional path, since the skim lists are not guaranteed
to exist for all events on the main path.
Reimplemented in CombinedSkim.
