exposure_record: a named list containing exposure records.
segment_prob_of_final_theta: the certainty that the final theta estimate belongs in the segment for the final theta estimate. This is 1 when exposure control method is ELIGIBILITY, BIGM, and a probability when exposure control method is BIGM-BAYESIAN.
segments_visited: visited segments. This means a set of all segments that all interim theta estimates for this examinee belonged to. The segment that the final theta estimate belonged to is not considered a visited segment.
eligibility_flag_in_final_theta_segment: a named list containing eligibility flags in the segment the final theta estimate belongs to.
x: an output_Shadow object, containing data for a single examinee.
simulation_constants: a named list containing simulation constants.
Returns
clipEligibilityRates returns an updated exposure record.
