/**
* Finds the set (i.e. no duplicates) of all elements contained in the first or

* 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
