/**
 * Finds the set (i.e. no duplicates) of all elements contained in the first or
 * second list, but not both. Duplication is determined according to the value
 * returned by applying the supplied predicate to two list elements.
 *
 * @func
 * @memberOf R
 * @since v0.19.0
 * @category Relation
 * @sig ((a, a) -> Boolean) -> [a] -> [a] -> [a]
 * @param {Function} pred A predicate used to test whether two items are equal.
 * @param {Array} list1 The first list.
 * @param {Array} list2 The second list.
 * @return {Array} The elements in `list1` or `list2`, but not both.
 * @see R.symmetricDifference, R.difference, R.differenceWith
 * @example
 *
 *      const eqA = R.eqBy(R.prop('a'));
 *      const l1 = [{a: 1}, {a: 2}, {a: 3}, {a: 4}];
 *      const l2 = [{a: 3}, {a: 4}, {a: 5}, {a: 6}];
 *      R.symmetricDifferenceWith(eqA, l1, l2); //=> [{a: 1}, {a: 2}, {a: 5}, {a: 6}]
