I added a zip(iterable1,...) to the iter module which returns an
Iterator that will iterate over the iterable objects simulatiously
similar to python's zip() method.

e.g.

map(zip([1,2,3],[3,2,1]), function(a,b){
return "%s:%s".format(a,b);
});
will result in:
["1:3", "2:2", "3:1"]

I have also added a natural string comparison method to the strings
module which can be used to sort string items in an array.
e.g.
["jsolait 1", "jsolait 11", "jsolait 2"].sort(strings.naturalCompare)
results in:
["jsolait 1", "jsolait 2", "jsolait 11"]
