Repeatedly calls iterator until test returns false;

* test(value) function : synchronous truth test to perform before each execution of iterator. value is the return value of the last iterator.
* iterator(value) function : A function or promise which is called each time test passes. value is the return value of the last iterator.

`js
var count = 0;
var arr = [];

// Iterator can be a normal function or a promise
Q.while(function() {
return count < 10;
}, function() {
count++;
arr.push(true);
}).then(function() {
console.log(arr.length); //= 10
});

// Can be used in a promise chain, passing the return
// value of the last function/iterator to the next
Q(2).while(function(total) {
return total <= 512;
}, function(total) {
return Q.delay(2).then(function() {
return total * 2;
});
}).then(function(finalTotal) {
console.log(finalTotal); //= 1024 (2^10)
});
`

The inverse of while -- repeatedly calls iterator until test returns true.

Calls the iterator n times, and accumulates results the same way you'd use map.

`js
var getPage = function(page) {
return Results.limit(10).offset(page * 10);
};

Q.times(10, getPage).then(function(pages) {
console.log(pages[0]); //= [res1, ..., res10]
});

Q(true).times(3, function(isCool) {
if (isCool) return "cool";
return "not cool";
}).then(function(arr) {
console.log(arr); //= ['cool','cool','cool']
});
