/**
 * @summary Discards ACDF tuples that are not related to the current authorization request.
 * @description
 *
 * Implementation of the algorithm outlined in ITU Recommendation X.501 (2016),
 * Section 18.8.3.
 *
 * ### Parameters
 *
 * @param {ACDFTupleExtended[]} tuples The tuples of inputs to the ACDF as described in
 *  ITU Recommendation X.501, Section 18.8.2. An array of five items:
 *  `( userClasses, authenticationLevel, protectedItems, grantsAndDenials, precedence )`
 * @param {ProtectedItem} request The thing that is being requested, which can
 *  be an entry, attribute type, or attribute value.
 * @param {number[]} operations The bit indices of the permissions that are
 *  being requested, divided by two. The permissions come from the definition of
 *  `GrantsAndDenials`. For clarification, an operation of 3 indicates a request
 *  for the remove permission.
 * @param {function} getEqualityMatcher A function that takes an object
 *  identifier and returns another function (if one can be found) that can be
 *  used to compare two values of the same attribute type.
 *  and returns a `boolean` indicating whether the user is a member of the group.
 * @returns {ACDFTupleExtended[]} Only the ACDF tuples that are relevant to this
 *  authorization request.
 * @function
