Returns an iterator which iterates over elements in an array-like object according to specified stride parameters.

@param {NonNegativeInteger} N - number of values to iterate
@param {Collection} src - input value
@param {integer} stride - stride length
@param {NonNegativeInteger} offset - starting index
@param {Function} [mapFcn] - function to invoke for each iterated value
@param {*} [thisArg] - execution context
@throws {TypeError} first argument must be a nonnegative integer
@throws {TypeError} second argument must be an array-like object
@throws {TypeError} third argument must be an integer
@throws {TypeError} fourth argument must be a nonnegative integer
@throws {TypeError} fifth argument must be a function
@returns {Iterator} iterator

@example
var values = [ 1, 2, 3, 4, 5, 6, 7, 8 ];

var N = 4;
var stride = -2;
var offset = 6;

var iter = stridedarray2iterator( N, values, stride, offset );

var v = iter.next().value;
// returns 7

v = iter.next().value;
// returns 5

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

// ...
