Force layout algorithm

[amergin]

Is it possible to force the layout algorithm to retrigger? I asked in https://github.com/ManifestWebDesign/angular-gridster/issues/458 whether it's possible to toggle the visibility of the items. As a continuation, it would be ideal to retrigger the layout algorithm to rearrange the items in the grid to take up the space freed from the hidden items.

The way I've forced the layout algorithm to retrigger is using the following code snippet:

var temp = $scope.items;
$scope.items = [];
$timeout(function() {
    $scope.items = temp;
});

which utilizes the fact that any updates to $scope.items will trigger a $digest cycle to occur. The $timeout call with no time specified ensures that the $digest cycle is triggered before the reset of items.
