Returns an iterator which iterates from right to left over each element in an array-like object view.

@param {Collection} src - input value
@param {integer} [begin=0] - starting **view** index (inclusive)
@param {integer} [end=src.length] - ending **view** index (non-inclusive)
@param {Function} [mapFcn] - function to invoke for each iterated value
@param {*} [thisArg] - execution context
@throws {TypeError} first argument must be an array-like object
@throws {TypeError} second argument must be either an integer (starting index) or a function
@throws {TypeError} third argument must be either an integer (ending index) or a function
@throws {TypeError} fourth argument must be a function
@returns {Iterator} iterator

@example
var iter = arrayview2iteratorRight( [ 1, 2, 3, 4 ], 1, 3 );

var v = iter.next().value;
// returns 3

v = iter.next().value;
// returns 2

var bool = iter.next().done;
// returns true
