incrementAlpha is an internal function for incrementing an exposure record variable.
Specifically, the a_ijk is incremented by one for administered items/sets.
incrementAlpha(
exposure_record,
segments_to_apply,
segment_prob,
x,
simulation_constants
)incrementAlpha returns an updated exposure record.
a named list containing exposure records.
which segments to apply the incrementing.
the amount of increment.
an output_Shadow object, containing data for a single examinee.
a named list containing simulation constants.
