func_documentation_string: This method is like `_.reduce` except that it iterates over elements
  of a `collection` from right to left.

  @param {Array|Object|string} collection The collection to iterate over.
  @param {Function} [callback=identity] The function called per iteration.
  @param {*} [accumulator] Initial value of the accumulator.
  @param {*} [thisArg] The `this` binding of `callback`.
  @returns {*} Returns the accumulated value.
  @example
  
  var list = [[0, 1], [2, 3], [4, 5]];
  var flat = _.reduceRight(list, function(a, b) { return a.concat(b); }, []);
  // => [4, 5, 2, 3, 0, 1]
