 * Returns the index of the last element of the list which matches the

 *
 * Acts as a transducer if a transformer is given in list position.

 * @func
 * @memberOf R
 * @since v0.1.1
 * @category List
 * @sig (a -> Boolean) -> [a] -> Number
 * @param {Function} fn The predicate function used to determine if the element is the
 * desired one.
 * @param {Array} list The array to consider.
 * @return {Number} The index of the element found, or `-1`.
 * @see R.transduce
 * @example
 *

 *      R.findLastIndex(R.propEq('a', 1))(xs); //=> 1
