/**
 * Creates a new function that, when invoked, caches the result of calling `fn`
 * for a given argument set and returns the result. Subsequent calls to the
 * memoized `fn` with the same argument set will not result in an additional
 * call to `fn`; instead, the cached result for that set of arguments will be
 * returned.
 *
 * Care must be taken when implementing key generation to avoid key collision,
 * or if tracking references, memory leaks and mutating arguments.
 *
 * @func
 * @memberOf R
 * @since v0.24.0
 * @category Function
 * @sig (*... -> String) -> (*... -> a) -> (*... -> a)
 * @param {Function} fn The function to generate the cache key.
 * @param {Function} fn The function to memoize.
 * @return {Function} Memoized version of `fn`.
 * @example
 *
 *      let count = 0;
 *      const factorial = R.memoizeWith(Number, n => {
 *        count += 1;
 *        return R.product(R.range(1, n + 1));
 *      });
 *      factorial(5); //=> 120
 *      factorial(5); //=> 120
 *      factorial(5); //=> 120
 *      count; //=> 1
